Chemical Structure
Description
The occurrence of 3-Amino-N-methyl-1H-pyrazole-4-carbimidothioic acid is closely related to a nitrile group, sulfur-containing functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 3-Amino-N-methyl-1H-pyrazole-4-carbimidothioic acid (CAS 178556-83-7), a certified reference material (molecular formula C5H8N4S, MW 156.21 g/mol) for analytical method development and quality control.
The molecular framework of 3-Amino-N-methyl-1H-pyrazole-4-carbimidothioic acid (C5H8N4S) is characterized by a nitrile group, sulfur-containing functionality. 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.
As a certified reference material (CRM), 3-Amino-N-methyl-1H-pyrazole-4-carbimidothioic acid 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.
