Chemical Structure

δ-Valerolactone-3,3,4,4-d4 CAS 42932-61-6 chemical structure

Description

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.

CATO supplies δ-Valerolactone-3,3,4,4-d4 (CAS 42932-61-6), a certified reference material (molecular formula C5H4D4O2, MW 104.14 g/mol) for analytical method development and quality control.

δ-Valerolactone-3,3,4,4-d4 (C5H4D4O2) 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. 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).

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.
