methyl (triphenylphosphoranylidene)acetate CAS 21204-67-1

Description

Compared with other compounds in its class, the molecular weight of 334.35 g/mol gives methyl (triphenylphosphoranylidene)acetate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

methyl (triphenylphosphoranylidene)acetate (CAS 21204-67-1) is a high-purity analytical reference standard with the molecular formula C21H19O2P and a molecular weight of 334.35 g/mol.

methyl (triphenylphosphoranylidene)acetate (C21H19O2P) contains a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage. 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.

CATO manufactures methyl (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.
