Chemical Structure
Description
CATO supplies 4-Methyl-N-(4,5,6,7-tetrahydrobenzo[b]thiophene-3-carbonyl)benzenesulfonohydrazide (CAS 136790-42-6), a certified reference material (molecular formula C16H18N2O3S2, MW 350.46 g/mol) for analytical method development and quality control.
Based on its molecular formula C16H18N2O3S2, 4-Methyl-N-(4,5,6,7-tetrahydrobenzo[b]thiophene-3-carbonyl)benzenesulfonohydrazide contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 350.46 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
