Chemical Structure
Description
2,4-Dichlorothiobenzamide (CAS 2775-38-4), molecular formula C7H5Cl2NS and molecular weight 206.09 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, sulfur-containing functionality, chlorine substitution, an aromatic ring system, 2,4-Dichlorothiobenzamide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 206.09 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 2,4-Dichlorothiobenzamide 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.
