Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies (2-Methoxy-2-oxoethyl)triphenylphosphonium chloride (CAS 2181-97-7), a certified reference material (molecular formula C21H20O2PCl, MW 370.81 g/mol) for analytical method development and quality control.
The molecular framework of (2-Methoxy-2-oxoethyl)triphenylphosphonium chloride (C21H20O2PCl) is characterized by a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage, chlorine 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), (2-Methoxy-2-oxoethyl)triphenylphosphonium 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.
