Chemical Structure

201996-20-5 Propionic acid-2.3-13C2 sodium salt Sodium propionate-2,3-13C2 CAS 201996-20-5 chemical structure

Description

Based on its molecular formula C[13C]2H5O2 Na, 201996-20-5 Propionic acid-2.3-13C2 sodium salt Sodium propionate-2,3-13C2 contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 84.05 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

201996-20-5 Propionic acid-2.3-13C2 sodium salt Sodium propionate-2,3-13C2 (CAS 201996-20-5), molecular formula C[13C]2H5O2 Na and molecular weight 84.05 g/mol, is a CATO reference standard with documented purity and traceability.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
