Chemical Structure

2-Hydroxy-4-(methylthio)butyric Acid (65-72% in Water) CAS 583-91-5 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 2-Hydroxy-4-(methylthio)butyric Acid (65-72% in Water).

CATO supplies 2-Hydroxy-4-(methylthio)butyric Acid (65-72% in Water) (CAS 583-91-5), a certified reference material (molecular formula C5H10O3S, MW 150.20 g/mol) for analytical method development and quality control.

Based on its molecular formula C5H10O3S, 2-Hydroxy-4-(methylthio)butyric Acid (65-72% in Water) contains a sulfone group, 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 150.20 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.
