Chemical Structure

(2-Hydroxy-5-methoxybenzyl)triphenylphosphoniumchloride CAS 153355-39-6 chemical structure

Description

The occurrence of (2-Hydroxy-5-methoxybenzyl)triphenylphosphoniumchloride is closely related to a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(2-Hydroxy-5-methoxybenzyl)triphenylphosphoniumchloride (CAS 153355-39-6) is a high-purity analytical reference standard with the molecular formula C26H24O2PCl and a molecular weight of 434.90 g/mol.

(2-Hydroxy-5-methoxybenzyl)triphenylphosphoniumchloride (C26H24O2PCl) contains a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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-Hydroxy-5-methoxybenzyl)triphenylphosphoniumchloride 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.
