Description
CATO manufactures 2-(3-(O-tolyl)propanoyl)benzothialdehyde 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.
2-(3-(O-tolyl)propanoyl)benzothialdehyde (CAS 898789-34-9), molecular formula C17H16OS and molecular weight 268.37 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, sulfur-containing functionality, a hydroxyl group, an ether linkage, 2-(3-(O-tolyl)propanoyl)benzothialdehyde is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 268.37 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
