5351-71-3 (2E)-2-[1-(Thiophen-2-yl)ethylidene]hydrazine-1-carbothioamide DTXSID00421377 CAS 5351-71-3

Description

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.

CATO supplies 5351-71-3 (2E)-2-[1-(Thiophen-2-yl)ethylidene]hydrazine-1-carbothioamide DTXSID00421377 (CAS 5351-71-3), a certified reference material (molecular formula C7H9N3S2, MW 199.30 g/mol) for analytical method development and quality control.

Structurally, 5351-71-3 (2E)-2-[1-(Thiophen-2-yl)ethylidene]hydrazine-1-carbothioamide DTXSID00421377 (C7H9N3S2) contains a nitrile group, sulfur-containing functionality, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 199.30 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
