N'-[(1E)-{4-[(4-chlorophenyl)sulfanyl]-3-nitrophenyl}methylidene]-1-methyl-3-(trifluoromethyl)-1H-thieno[2,3-c]pyrazole-5-carbohydrazide CAS 865659-85-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N'-[(1E)-{4-[(4-chlorophenyl)sulfanyl]-3-nitrophenyl}methylidene]-1-methyl-3-(trifluoromethyl)-1H-thieno[2,3-c]pyrazole-5-carbohydrazide.

CATO supplies N'-[(1E)-{4-[(4-chlorophenyl)sulfanyl]-3-nitrophenyl}methylidene]-1-methyl-3-(trifluoromethyl)-1H-thieno[2,3-c]pyrazole-5-carbohydrazide (CAS 865659-85-4), a certified reference material (molecular formula C21H13ClF3N5O3S2, MW 539.94 g/mol) for analytical method development and quality control.

Structurally, N'-[(1E)-{4-[(4-chlorophenyl)sulfanyl]-3-nitrophenyl}methylidene]-1-methyl-3-(trifluoromethyl)-1H-thieno[2,3-c]pyrazole-5-carbohydrazide (C21H13ClF3N5O3S2) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 16.0, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 539.94 g/mol, it falls into the moderately-high-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.

CATO manufactures N'-[(1E)-{4-[(4-chlorophenyl)sulfanyl]-3-nitrophenyl}methylidene]-1-methyl-3-(trifluoromethyl)-1H-thieno[2,3-c]pyrazole-5-carbohydrazide 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.
