Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Fluorobenzyl triphenylphosphonium chloride.
3-Fluorobenzyl triphenylphosphonium chloride (CAS 55128-97-7), molecular formula C25H21FPCl and molecular weight 406.87 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3-Fluorobenzyl triphenylphosphonium chloride (C25H21FPCl) contains organophosphorus functionality, fluorine/chlorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 14.5, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 406.87 g/mol, it falls into the moderately-high-molecular-weight range. 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.
CATO manufactures 3-Fluorobenzyl triphenylphosphonium 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.
