Chemical Structure
Description
The occurrence of N-(3-Chlorophenyl)hydrazinecarbothioamide is closely related to a nitrile group, sulfur-containing functionality, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
N-(3-Chlorophenyl)hydrazinecarbothioamide (CAS 42135-76-2) is a high-purity analytical reference standard with the molecular formula C7H8ClN3S and a molecular weight of 201.68 g/mol.
The molecular framework of N-(3-Chlorophenyl)hydrazinecarbothioamide (C7H8ClN3S) is characterized by a nitrile group, sulfur-containing functionality, chlorine substitution, an aromatic ring system. 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), N-(3-Chlorophenyl)hydrazinecarbothioamide 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.
