Chemical Structure
Description
CATO manufactures 2-Hydroxy-3-(tritylthio)propanoic acid 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.
CATO supplies 2-Hydroxy-3-(tritylthio)propanoic acid (CAS 1357287-50-3), a certified reference material (molecular formula C22H20O3S, MW 364.46 g/mol) for analytical method development and quality control.
Owing to a steroid core, a sulfone group, a hydroxyl group, an ether linkage, 2-Hydroxy-3-(tritylthio)propanoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 364.46 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.
