Coumaphos-d10 CAS 287397-86-8

Description

Compared with other compounds in its class, the molecular weight of 372.83 g/mol gives Coumaphos-d10 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Coumaphos-d10 (CAS 287397-86-8) is a high-purity analytical reference standard with the molecular formula C14H6D10ClO5PS and a molecular weight of 372.83 g/mol.

Coumaphos-d10 (C14H6D10ClO5PS) contains deuterium isotope labeling, a sulfone group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
