Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 491.36 g/mol gives (2-(Benzyloxy)-2-oxoethyl)triphenylphosphonium bromide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies (2-(Benzyloxy)-2-oxoethyl)triphenylphosphonium bromide (CAS 78385-36-1), a certified reference material (molecular formula C27H24O2PBr, MW 491.36 g/mol) for analytical method development and quality control.
The molecular framework of (2-(Benzyloxy)-2-oxoethyl)triphenylphosphonium bromide (C27H24O2PBr) is characterized by a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
As a certified reference material (CRM), (2-(Benzyloxy)-2-oxoethyl)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.
