Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-Chloro-5-(pentafluoro-lambda6-sulfanyl)benzaldehyde (CAS 1431329-76-8), molecular formula C7H4ClF5OS and molecular weight 266.62 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 2-Chloro-5-(pentafluoro-lambda6-sulfanyl)benzaldehyde is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 266.62 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).
CATO manufactures 2-Chloro-5-(pentafluoro-lambda6-sulfanyl)benzaldehyde 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.
