Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Pent-4-en-1-yltriphenylphosphonium bromide.
Pent-4-en-1-yltriphenylphosphonium bromide (CAS 56771-29-0) is a high-purity analytical reference standard with the molecular formula C23H24PBr and a molecular weight of 411.32 g/mol.
Based on its molecular formula C23H24PBr, Pent-4-en-1-yltriphenylphosphonium bromide contains organophosphorus functionality, bromine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 411.32 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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 Pent-4-en-1-yltriphenylphosphonium bromide 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.
