Description
As a certified reference material (CRM), (2-Hydroxy-3-phenoxypropyl)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.
CATO supplies (2-Hydroxy-3-phenoxypropyl)triphenylphosphonium bromide (CAS 16315-61-0), a certified reference material (molecular formula C27H26O2PBr, MW 493.38 g/mol) for analytical method development and quality control.
Based on its molecular formula C27H26O2PBr, (2-Hydroxy-3-phenoxypropyl)triphenylphosphonium bromide contains a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 493.38 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
