Description
CATO manufactures Bis(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.
CATO supplies Bis(4-methoxyphenyl)chlorophosphine (CAS 13685-30-8), a certified reference material (molecular formula C14H14ClO2P, MW 280.69 g/mol) for analytical method development and quality control.
Owing to organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system, Bis(4-methoxyphenyl)chlorophosphine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 280.69 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
