(S)-(-)-alpha-Hydroxy-gamma-butyrolactone CAS 52079-23-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (S)-(-)-alpha-Hydroxy-gamma-butyrolactone.

CATO supplies (S)-(-)-alpha-Hydroxy-gamma-butyrolactone (CAS 52079-23-9), a certified reference material (molecular formula C4H6O3, MW 102.09 g/mol) for analytical method development and quality control.

Based on its molecular formula C4H6O3, (S)-(-)-alpha-Hydroxy-gamma-butyrolactone contains 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 102.09 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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.
