Chemical Structure

1,2-Propanediol-d3 CAS 70195-21-0 chemical structure

Description

The occurrence of 1,2-Propanediol-d3 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.

1,2-Propanediol-d3 (CAS 70195-21-0), molecular formula C3H5D3O2 and molecular weight 79.11 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C3H5D3O2, 1,2-Propanediol-d3 contains deuterium isotope labeling, 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 79.11 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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.
