Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 177.23 g/mol gives 1H-Indazole-3-carbothioamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1H-Indazole-3-carbothioamide (CAS 28751-69-1), molecular formula C8H7N3S and molecular weight 177.23 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1H-Indazole-3-carbothioamide (C8H7N3S) is characterized by a nitrogen-containing heterocyclic scaffold, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 1H-Indazole-3-carbothioamide 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.
