Acetonyl triphenylphosphonium bromide CAS 2236-01-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Acetonyl triphenylphosphonium bromide.

Acetonyl triphenylphosphonium bromide (CAS 2236-01-3), molecular formula C21H20OPBr and molecular weight 399.27 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage, bromine substitution, Acetonyl triphenylphosphonium bromide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 399.27 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.

As a certified reference material (CRM), Acetonyl triphenylphosphonium bromide 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.
