What it is Filled
Calcium fumarate is the calcium salt of fumaric acid, consisting of calcium cations and fumarate dianions, with the anhydrous formula CaC4H2O4.
In scope
- Calcium and fumarate identity, ionic stoichiometry and distinction between anhydrous and hydrated forms
- Batch composition, assay basis, water content and relevant impurities
- Physical form, dissolution behaviour and thermal behaviour under recorded conditions
- Grade-specific specifications, traceability and evidence of conformity
- Handling, storage and intended-use constraints supported by applicable evidence
Out of scope
- Fumaric acid, maleic acid and their separate substance models
- Other calcium salts and fumarate salts with other counterions
- Finished foods, supplements, medicines or mixtures containing calcium fumarate
- Manufacturing equipment and complete synthesis-process models
- Clinical calcium requirements, patient treatment and dosing decisions
Why it exists Filled
Enable an agent to recognise calcium fumarate, assess the identity and fitness of a particular material, and determine which handling or use decisions its evidence supports.
Distinguishing features Filled
- Establish that both calcium and fumarate are present; calcium content alone cannot distinguish this material from another calcium salt.
- Confirm the fumarate anion's trans configuration to distinguish it from the corresponding maleate material.
- Check calcium-to-fumarate stoichiometry and acid-base composition to distinguish the declared salt from an acid salt or a mixture containing free fumaric acid.
- Determine whether measured water represents a hydrate, adsorbed moisture or another contribution before comparing formula masses and assay results.
- Distinguish an identified calcium fumarate substance batch from a formulation whose label merely lists calcium fumarate as an ingredient.
What robots and AI may and may not do Filled
Must not
- Use non-food-grade material in food or supplements.
- Make health claims for products containing it that the regulator has not authorized.
- Mislabel its content in a product.
Only with a human decision
- Changing a formulation sold to the public.
May
- Identify calcium fumarate from labels, identifiers and certificates.
- Report its permitted uses in food or supplements in a stated country from official sources.
- Check a lot against its food- or pharmaceutical-grade specification.
Moral aspects Filled
- Supplements are bought on trust; accurate labelling and claims protect consumers.
Who is affected
- Consumers
- Food and supplement producers
Owners Filled
Steward
The producer that uses it; food safety authorities set the rules.
