Calcium alpha-ketoglutarate (Ca-AKG) 98% supplier specification
Nutrition BioTech is a bulk calcium alpha-ketoglutarate (Ca-AKG) ingredient supplier and manufacturer, supplying Ca-AKG monohydrate (CAS 71686-01-6) at 98% minimum as CalciAKG™, produced by synthesis and crystallisation, for B2B nutraceutical and longevity-category formulation.
Ca-AKG is a gram-scale calcium salt supplied as the monohydrate, so three numbers drive every formulation decision: the assay, the water content and the elemental calcium content, all of which come off the Certificate of Analysis. Label maths should be run on the monohydrate basis rather than the anhydrous basis.
| Ingredient name | Calcium alpha-ketoglutarate (Ca-AKG) 98%, monohydrate — CalciAKG™ |
|---|---|
| Synonyms | Ca-AKG; calcium AKG; calcium 2-oxoglutarate monohydrate; calcium 2-oxopentanedioate; alpha-ketoglutaric acid calcium salt |
| CAS number | 71686-01-6 — the CAS number carried on our specification sheet for the monohydrate |
| Molecular formula | C5H4CaO5 · H2O (monohydrate) — C5H4CaO5 on the anhydrous basis |
| Molecular weight | 202.18 g/mol (monohydrate) · 184.16 g/mol (anhydrous basis) |
| Assay / purity | 98% minimum, stated on the Certificate of Analysis for each lot together with the assay method. |
| Hydration & calcium content | Supplied as the monohydrate. Water content and elemental calcium content are stated on the Certificate of Analysis and must be used for label calculations rather than assumed. |
| Production route | Organic synthesis: neutralisation of alpha-ketoglutaric acid with a calcium source, followed by crystallisation and drying. |
| Appearance | White to off-white crystalline powder |
| Solubility | Slightly soluble in water; insoluble in ethanol. |
| Typical applications | Capsules, tablets and powder blends for B2B nutraceutical manufacturing. Servings are gram-scale, so label space and tablet weight should be checked early. |
| Documentation | Certificate of Analysis, specification sheet, heavy metals, microbiological testing, residual solvents, allergen statement, GMO statement, water and calcium content, particle size and stability data |
| Quality system | ISO 22000:2018, FSSC 22000, HACCP and GMP (certificates provided on request) |
| Supplier | Nutrition BioTech, 1601 W. Mission Blvd, Suite 103 (DL#29), Pomona, CA 91766, United States |
