Chemical Structure
Description
The occurrence of Diphenylphosphinic Chloride is closely related to organophosphorus functionality, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Diphenylphosphinic Chloride (CAS 1499-21-4), molecular formula C12H10ClOP and molecular weight 236.63 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to organophosphorus functionality, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, Diphenylphosphinic Chloride is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 236.63 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 Diphenylphosphinic Chloride 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.
