Isovaleric Acid-d9 CAS 344298-81-3 chemical structure

Description

CATO supplies Isovaleric Acid-d9 (CAS 344298-81-3), a certified reference material (molecular formula C5HD9O2, MW 111.19 g/mol) for analytical method development and quality control.

Owing to deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage, Isovaleric Acid-d9 is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 111.19 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.
