Description
CATO manufactures Tributyl(4-methylbenzyl)phosphonium 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.
Tributyl(4-methylbenzyl)phosphonium chloride (CAS 1519-41-1) is a high-purity analytical reference standard with the molecular formula C20H36PCl and a molecular weight of 342.93 g/mol.
Structurally, Tributyl(4-methylbenzyl)phosphonium chloride (C20H36PCl) contains organophosphorus functionality, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.5, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 342.93 g/mol, it falls into the moderately-high-molecular-weight range. 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.
