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 (Hydroxymethyl)triphenylphosphonium (tetrafluoroborate).
CATO supplies (Hydroxymethyl)triphenylphosphonium (tetrafluoroborate) (CAS 2340-49-0), a certified reference material (molecular formula C19H18OPBF3F, MW 380.13 g/mol) for analytical method development and quality control.
The molecular framework of (Hydroxymethyl)triphenylphosphonium (tetrafluoroborate) (C19H18OPBF3F) is characterized by a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage, fluorine 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 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.
