Chemical Structure
Description
The occurrence of 4-Methyl-N-[(8-methyl-8H-thieno[2,3-b]indol-2-yl)carbonyl]benzenesulfonohydrazide is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Methyl-N-[(8-methyl-8H-thieno[2,3-b]indol-2-yl)carbonyl]benzenesulfonohydrazide (CAS 477860-44-9) is a high-purity analytical reference standard with the molecular formula C19H17N3O3S2 and a molecular weight of 399.49 g/mol.
The molecular framework of 4-Methyl-N-[(8-methyl-8H-thieno[2,3-b]indol-2-yl)carbonyl]benzenesulfonohydrazide (C19H17N3O3S2) is characterized by a steroid core, an amide group, a sulfone group, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
