(S)-Sitagliptin Phosphate - USP Certified Reference Standard (CRS) is a high-purity pharmaceutical standard used for analytical validation in drug development and quality control of sitagliptin-containing formulations. Sitagliptin is the (R)-enantiomer, and this (S)-enantiomer (ent-sitagliptin) is its inactive counterpart, so USP uses this reference material to identify and control the enantiomeric impurity in chiral purity testing of sitagliptin phosphate. CAS: 823817-58-9 | Molecular formula: C16H18F6N5O5P | Molecular weight: 505.31 g/mol | Storage: 2–8°C (protected from light) | Signal word: Warning (irritant, follow safety data sheet). Molekula supplies (S)-Sitagliptin Phosphate - USP CRS from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
