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 (2,5-Dimethoxybenzyl)triphenylphosphonium chloride.
(2,5-Dimethoxybenzyl)triphenylphosphonium chloride (CAS 174655-16-4), molecular formula C27H26O2PCl and molecular weight 448.93 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, chlorine substitution, (2,5-Dimethoxybenzyl)triphenylphosphonium chloride is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 448.93 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.
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
