Chemical Structure
Description
Calcium Thioglycolate Trihydrate (CAS 5793-98-6) is a high-purity analytical reference standard with the molecular formula C2H3O2SCaH2O and a molecular weight of 149.20 g/mol.
Owing to a sulfone group, a carboxylic acid group, an ether linkage, Calcium Thioglycolate Trihydrate is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 149.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
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 Calcium Thioglycolate Trihydrate 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.
