Chemical Structure
Description
The occurrence of N-ethyl-2-(thiophene-2-carbonyl)hydrazine-1-carbothioamide is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
N-ethyl-2-(thiophene-2-carbonyl)hydrazine-1-carbothioamide (CAS 306954-98-3), molecular formula C8H11N3OS2 and molecular weight 229.32 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N-ethyl-2-(thiophene-2-carbonyl)hydrazine-1-carbothioamide (C8H11N3OS2) is characterized by a nitrogen-containing heterocyclic scaffold, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
CATO manufactures N-ethyl-2-(thiophene-2-carbonyl)hydrazine-1-carbothioamide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
