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 (2-Nitrobenzyl)triphenylphosphonium bromide hydrate.
(2-Nitrobenzyl)triphenylphosphonium bromide hydrate (CAS 1922975-65-2), molecular formula C25H21NO2PBrH2O and molecular weight 496.34 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (2-Nitrobenzyl)triphenylphosphonium bromide hydrate (C25H21NO2PBrH2O) contains a steroid core, an amide group, a phosphonate group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 14.5, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 496.34 g/mol, it falls into the moderately-high-molecular-weight range. 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.
As a certified reference material (CRM), (2-Nitrobenzyl)triphenylphosphonium bromide hydrate 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.
