Chemical Structure

Diflunisal-d3 CAS 1286107-99-0 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 250.20 g/mol gives Diflunisal-d3 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Diflunisal-d3 (CAS 1286107-99-0), a certified reference material (molecular formula C13H8F2O3, MW 250.20 g/mol) for analytical method development and quality control.

Diflunisal-d3 (C13H8F2O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. It is notably hygroscopic, 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. 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.

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.
