Calcium phosphate is an inorganic compound primarily used as a dietary supplement to provide calcium and phosphorus, essential minerals for bone health and metabolic function. It also serves as a food additive (E341), an anticaking agent in powdered products, and a buffering agent in pharmaceuticals. Industrially, it is used to make fertilizers and phosphoric acid, in glass, porcelain and ceramics manufacturing, and as a mineral additive in animal feeds. This white, odorless powder is non-hazardous with no signal word classification, ensuring safe handling for industrial, nutritional, and pharmaceutical applications. Molekula supplies calcium phosphate from research to bulk quantities with full documentation and ISO 9001:2015 traceability.

Frequently asked questions
What is calcium phosphate commonly used for?
Calcium phosphate is primarily used in food and pharmaceutical industries as a nutritional supplement (e.g., calcium source in fortified foods), as an excipient in tablets, and in dental cements.
What is the chemical formula and molecular weight of calcium phosphate?
This product (CAS 10103-46-5) is tricalcium phosphate (tribasic calcium phosphate), Ca₃(PO₄)₂, with a molecular weight of approximately 310.18 g/mol. Other calcium phosphates, such as dibasic calcium phosphate dihydrate (CaHPO₄·2H₂O, CAS 7789-77-7), are separate compounds with different formulas and molecular weights.
How should calcium phosphate be stored?
Store in a cool, dry place in a tightly sealed container to prevent moisture absorption. Avoid contamination and exposure to strong acids or alkalis.
What grades of calcium phosphate does Molekula supply?
Molekula supplies food-grade (USP/NF/FCC compliant) and pharmaceutical-grade calcium phosphate, depending on the application requirements.
Can Molekula supply calcium phosphate in bulk quantities?
Yes, we offer bulk packaging options (e.g., 25kg bags, 50kg drums, or larger custom quantities) for industrial, food, or pharmaceutical use—subject to minimum order quantities.
What documentation is provided with a calcium phosphate order?
Each order includes a Certificate of Analysis (CoA), Material Safety Data Sheet (MSDS), and, for food/pharma grades, USP/NF/FCC compliance documentation if applicable.
Molekula has supplied fine chemicals and biochemicals since 2000 from ISO 9001:2015 and ISO 14001:2015 certified facilities. Every dispatched batch is logged with a batch number and matched to a Certificate of Analysis, and Safety Data Sheets are available in five languages.
