Chemical Structure
Description
(±)-1,2-Propanediol-(OD)2 (C3H6D2O2) 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.
(±)-1,2-Propanediol-(OD)2 (CAS 58161-11-8), molecular formula C3H6D2O2 and molecular weight 78.11 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.
