Description

CATO supplies (E)-3-(3,4-dimethoxyphenyl)-1,6-dimethyl-1,5,6,7-tetrahydro-4H-indazol-4-one O-methyl oxime (CAS 1024720-16-8), a certified reference material (molecular formula C18H23N3O3, MW 329.39 g/mol) for analytical method development and quality control.

(E)-3-(3,4-dimethoxyphenyl)-1,6-dimethyl-1,5,6,7-tetrahydro-4H-indazol-4-one O-methyl oxime (C18H23N3O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 (E)-3-(3,4-dimethoxyphenyl)-1,6-dimethyl-1,5,6,7-tetrahydro-4H-indazol-4-one O-methyl oxime 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.
