Ethyl 2-chloro-2-(triphenylphosphoranylidene)acetate CAS 31459-99-1

Description

The occurrence of Ethyl 2-chloro-2-(triphenylphosphoranylidene)acetate 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.

CATO supplies Ethyl 2-chloro-2-(triphenylphosphoranylidene)acetate (CAS 31459-99-1), a certified reference material (molecular formula C22H20ClO2P, MW 382.82 g/mol) for analytical method development and quality control.

Owing to a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage, chlorine substitution, Ethyl 2-chloro-2-(triphenylphosphoranylidene)acetate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 382.82 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

CATO manufactures Ethyl 2-chloro-2-(triphenylphosphoranylidene)acetate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
