2-(Diphenylphosphoryl)cyclohept-1-ene-1-carboxylic acid CAS 885456-93-9

Description

The occurrence of 2-(Diphenylphosphoryl)cyclohept-1-ene-1-carboxylic acid is closely related to a steroid core, a phosphonate group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 2-(Diphenylphosphoryl)cyclohept-1-ene-1-carboxylic acid (CAS 885456-93-9), a certified reference material (molecular formula C20H21O3P, MW 340.35 g/mol) for analytical method development and quality control.

Based on its molecular formula C20H21O3P, 2-(Diphenylphosphoryl)cyclohept-1-ene-1-carboxylic acid contains a steroid core, a phosphonate group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 340.35 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
