Chemical Structure

Sulfathiazole-13C6 CAS 1196157-72-8 chemical structure

Description

The occurrence of Sulfathiazole-13C6 is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Sulfathiazole-13C6 (CAS 1196157-72-8), a certified reference material (molecular formula C3[13C]6H9N3O2S2, MW 261.27 g/mol) for analytical method development and quality control.

Based on its molecular formula C3[13C]6H9N3O2S2, Sulfathiazole-13C6 contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 261.27 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), Sulfathiazole-13C6 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.
