Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Bis(2-methoxyphenyl)phosphine.
Bis(2-methoxyphenyl)phosphine (CAS 10177-79-4), molecular formula C14H27O2P and molecular weight 258.34 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, Bis(2-methoxyphenyl)phosphine is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 258.34 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 Bis(2-methoxyphenyl)phosphine 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.
