Cefadroxil-d4 CAS CATO-C4X-122411

Description

Compared with other compounds in its class, the molecular weight of 385.43 g/mol gives Cefadroxil-d4 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Cefadroxil-d4 (CAS CATO-C4X-122411), a certified reference material (molecular formula C16H13D4N3O5SH2O, MW 385.43 g/mol) for analytical method development and quality control.

Owing to deuterium isotope labeling, a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Cefadroxil-d4 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 385.43 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
