Chemical Structure

Propionic-2,2-d2 acid CAS 19136-91-5 chemical structure

Description

The occurrence of Propionic-2,2-d2 acid is closely related to deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Propionic-2,2-d2 acid (CAS 19136-91-5), a certified reference material (molecular formula C3H4D2O2, MW 76.09 g/mol) for analytical method development and quality control.

Propionic-2,2-d2 acid (C3H4D2O2) contains deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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.
