Chemical Structure
Description
As a certified reference material (CRM), N-Acetylsulfamerazine 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.
N-Acetylsulfamerazine (CAS 127-73-1), molecular formula C13H14N4O3S and molecular weight 306.34 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N-Acetylsulfamerazine (C13H14N4O3S) is characterized by 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
