Chemical Structure

2,3-Butanedione-d6 CAS 22026-37-5 chemical structure

Description

CATO supplies 2,3-Butanedione-d6 (CAS 22026-37-5), a certified reference material (molecular formula C4D6O2, MW 92.13 g/mol) for analytical method development and quality control.

Owing to deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage, 2,3-Butanedione-d6 is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 92.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
