Chemical Structure

But-2-en-1-yltriphenylphosphonium chloride CAS 13138-25-5 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 But-2-en-1-yltriphenylphosphonium chloride.

But-2-en-1-yltriphenylphosphonium chloride (CAS 13138-25-5), molecular formula C22H22PCl and molecular weight 352.84 g/mol, is a CATO reference standard with documented purity and traceability.

But-2-en-1-yltriphenylphosphonium chloride (C22H22PCl) contains organophosphorus functionality, chlorine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

As a certified reference material (CRM), But-2-en-1-yltriphenylphosphonium chloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
