Chemical identity Establish what counts as darolutamide and how a record or sample demonstrates that identity.
Molecular reference
Connect the registry entry to an authoritative chemical identity.
Structure and identifiers
The FDA label supplies the chemical name, formula and molecular weight used as initial identity anchors. Identifier mappings still require verification. [FDA prescribing information, section 11](https://www.accessdata.fda.gov/drugsatfda_docs/label/2025/212099s008lbl.pdf).
- Which authoritative structure representation, including specified stereochemistry, defines darolutamide for this registry entry? definition
- Which verified CAS, PubChem, UNII or EC records match that same substance definition? provenance
Stereochemical boundary
Determine which stereochemical compositions belong to the registered substance.
Stereoisomer acceptance
Record stereoisomer assignments, proportions and reference-material evidence without assuming an unverified acceptance ratio.
- Which stereoisomers and proportion limits define an acceptable darolutamide material? definition
- Which validated stereoselective method establishes the composition of this sample? measurement
Composition and quality Determine how much darolutamide a material contains and what accompanies it.
Content and matrix
Separate active-substance quantity from solvent, moisture and formulation mass.
Assay basis
Record darolutamide content with its calculation basis, sample matrix and uncertainty.
- What darolutamide mass fraction is measured, and is it reported as-is, dry or solvent-free? measurement

Physical state and stability Represent darolutamide's material form and behavior under specified conditions.
Solid form and dissolution
Relate physical characterization to solvent preparation.
Conditional physical properties
The label describes a crystalline powder with practical aqueous insolubility; quantitative preparation decisions need condition-specific measurements. [FDA prescribing information, section 11](https://www.accessdata.fda.gov/drugsatfda_docs/label/2025/212099s008lbl.pdf).
- Which diffraction or thermal measurements establish this sample's solid form? measurement
- What solubility is measured in the proposed medium at the relevant pH, temperature and equilibration time? measurement
Storage and change
Track whether material history has altered composition or physical form.
Stability-supported disposition
Use bulk-substance or solution stability evidence to define storage and retest decisions; do not transfer tablet shelf-life claims automatically.
- Which studies support this darolutamide material's container, temperature, light and moisture conditions? provenance
- What excursion, assay change or physical-form change triggers retesting or rejection? action
Biological activity and transformation Connect chemical identity to experimentally supported activity and biological transformation.
Receptor activity
Record what an activity experiment establishes about the tested material.
Androgen receptor inhibition
Darolutamide inhibits androgen receptor signaling. Quantitative claims require assay context and identified test material. [FDA prescribing information, section 12.1](https://www.accessdata.fda.gov/drugsatfda_docs/label/2025/212099s008lbl.pdf).
- Which receptor variant, ligand concentration and biological system underpin the reported inhibition? measurement
- Was the tested material authenticated darolutamide, a separated stereoisomer or a mixture containing other active substances? provenance
Parent-metabolite separation
Keep biological transformation relationships distinct from substance identity.
Ketodarolutamide relationship
Ketodarolutamide is an active metabolite and requires a distinct identity when interpreting analytical or activity results. [FDA prescribing information, section 12.1](https://www.accessdata.fda.gov/drugsatfda_docs/label/2025/212099s008lbl.pdf).
- Does the reported concentration distinguish darolutamide from ketodarolutamide and other measured analytes? boundary
- Which experiment supports the transformation relationship and the contribution attributed to each analyte? provenance
Handling and use constraints Determine which handling and use decisions are justified for the particular darolutamide material.
Occupational handling
Connect hazard evidence to operations involving powder or solution.
Exposure control evidence
Record applicable safety data and exposure assessments; clinical warnings alone do not assign a bulk-material GHS classification or occupational limit.
- Which current supplier safety data and jurisdiction-specific assessments apply to this darolutamide material? provenance
- What documented containment, protective equipment and waste controls apply to weighing, dissolution and spill cleanup? action
Regulatory and product links
Connect substance records to permitted uses without merging them with product authorizations.
Use eligibility
Keep batch qualification, supplier grade and linked medicinal-product authorization as separate evidence for a proposed use.
- Which jurisdiction, date and intended use govern this material's eligibility? boundary
- What qualification evidence is required before this batch can enter the proposed research or pharmaceutical workflow? action

What it is Filled
Darolutamide is a nonsteroidal androgen receptor antagonist used as an active pharmaceutical ingredient in oral treatments for prostate cancer.
In scope
- Molecular and stereochemical identity, with verified identifier mappings
- Darolutamide content, related substances and batch-specific purity
- Solid form, solubility, stability and relevant measurement conditions
- Androgen receptor activity and relationships to metabolites
- Evidence governing material handling, grade and permitted use
Out of scope
- Nubeqa tablets, their excipients, packaging and finished-product release
- Patient diagnosis, treatment selection and individualized dosing
- Prostate cancer and androgen receptor biology as independent models
- Manufacturing routes, equipment and production operations
- Ketodarolutamide as an independently characterized substance
Why it exists Filled
Enable an agent to recognize darolutamide, assess the identity and condition of a material sample, and determine whether evidence supports its proposed handling or use.
Distinguishing features Filled
- Require a structure-specific identity match; the reported formula C19H19ClN6O2 and molar mass 398.85 g/mol are supporting checks rather than unique identifiers.
- Check stereochemical composition against an authenticated darolutamide reference; a matching formula or nonchiral assay alone cannot establish equivalence.
- Distinguish parent darolutamide from ketodarolutamide analytically; shared androgen receptor activity does not establish chemical identity.
- Distinguish bulk darolutamide from a darolutamide-containing tablet or solution by recording matrix and active-substance content.
- Distinguish darolutamide from other androgen receptor inhibitors through chemical identity rather than therapeutic class.
What robots and AI may and may not do Filled
