83587-75-1 Propionic acid-1,2-13C2 sodium salt Sodium propionate-1,2-13C2 CAS 83587-75-1

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 83587-75-1 Propionic acid-1,2-13C2 sodium salt Sodium propionate-1,2-13C2.

83587-75-1 Propionic acid-1,2-13C2 sodium salt Sodium propionate-1,2-13C2 (CAS 83587-75-1), molecular formula C[13C]2H5O2 Na and molecular weight 84.05 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 83587-75-1 Propionic acid-1,2-13C2 sodium salt Sodium propionate-1,2-13C2 (C[13C]2H5O2 Na) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
