Sulfathiazole-D4 CAS 1020719-89-4

Description

Compared with other compounds in its class, the molecular weight of 259.34 g/mol gives Sulfathiazole-D4 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Sulfathiazole-D4 (CAS 1020719-89-4), molecular formula C9H5D4N3O2S2 and molecular weight 259.34 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Sulfathiazole-D4 (C9H5D4N3O2S2) is characterized by deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

As a certified reference material (CRM), Sulfathiazole-D4 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
