Chemical Structure
Description
The molecular framework of n-(1,2,3-Thiadiazol-4-ylmethylidene)hydroxylamine (C3H3N3OS) is characterized by an amide group, sulfur-containing functionality, 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).
n-(1,2,3-Thiadiazol-4-ylmethylidene)hydroxylamine (CAS 162640-72-4) is a high-purity analytical reference standard with the molecular formula C3H3N3OS and a molecular weight of 129.14 g/mol.
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), n-(1,2,3-Thiadiazol-4-ylmethylidene)hydroxylamine 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.
