Betaine Citrate

About Betaine Citrate

Betaine Citrate is a high-purity reference standard of Betaine carrying the CAS registry number 17671-50-0. Its molecular formula is C11H19NO9 and its molecular weight is 309.27 g/mol.

The product is provided as a solid. Reference materials should be stored sealed and away from light and moisture, as specified on the accompanying COA. Under GHS it is labelled “Warning”, so handle it with suitable PPE and consult the SDS.

Laboratories use this Betaine standard for identity and assay testing, system suitability checks and method validation supporting ANDA and DMF filings. Typical end-use sectors are pharmaceutical manufacturing and academic and industrial research.

Standard pack sizes are 10 mg, 25 mg, 50 mg and 100 mg, and every batch ships with a Certificate of Analysis (COA) and we export worldwide.
