Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Bis(3,5-dimethyl-4-methoxyphenyl)chlorophosphine (CAS 136802-85-2), molecular formula C18H22ClO2P and molecular weight 336.79 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage, chlorine substitution, Bis(3,5-dimethyl-4-methoxyphenyl)chlorophosphine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 336.79 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).
CATO manufactures Bis(3,5-dimethyl-4-methoxyphenyl)chlorophosphine 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.
