Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-phenyl-2-(thiophene-2-carbonyl)hydrazine-1-carbothioamide.
N-phenyl-2-(thiophene-2-carbonyl)hydrazine-1-carbothioamide (CAS 64612-84-6), molecular formula C12H11N3OS2 and molecular weight 277.37 g/mol, is a CATO reference standard with documented purity and traceability.
N-phenyl-2-(thiophene-2-carbonyl)hydrazine-1-carbothioamide (C12H11N3OS2) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
