Chemical Structure
Description
3-Amino-1-cyclopentyl-1h-pyrazole-4-carbothioamide (CAS 1421602-06-3), molecular formula C9H14N4S and molecular weight 210.30 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-Amino-1-cyclopentyl-1h-pyrazole-4-carbothioamide (C9H14N4S) 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), 3-Amino-1-cyclopentyl-1h-pyrazole-4-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.
