N-(2-(tert-Butyl)-2,6-dihydro-4H-thieno[3,4-c]pyrazol-3-yl)-4-isopropoxybenzamide CAS 476459-21-9

Description

The molecular framework of N-(2-(tert-Butyl)-2,6-dihydro-4H-thieno[3,4-c]pyrazol-3-yl)-4-isopropoxybenzamide (C19H25N3O2S) 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.

N-(2-(tert-Butyl)-2,6-dihydro-4H-thieno[3,4-c]pyrazol-3-yl)-4-isopropoxybenzamide (CAS 476459-21-9), molecular formula C19H25N3O2S and molecular weight 359.49 g/mol, is a CATO reference standard with documented purity and traceability.
