Chemical Structure
Description
CATO supplies Methyl (S)-4-chloro-3-hydroxybutanoate (CAS 86728-93-0), a certified reference material (molecular formula C5H9ClO3, MW 152.58 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, Methyl (S)-4-chloro-3-hydroxybutanoate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 152.58 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 manufactures Methyl (S)-4-chloro-3-hydroxybutanoate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
