2-Amino-N-(1,5-dimethyl-3-oxo-2-phenyl-2,3-dihydro-1h-pyrazol-4-yl)-4,5,6,7-tetrahydro-1-benzothiophene-3-carboxamide (CAS 258843-88-8), molecular formula C20H22N4O2S and molecular weight 382.48 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Amino-N-(1,5-dimethyl-3-oxo-2-phenyl-2,3-dihydro-1h-pyrazol-4-yl)-4,5,6,7-tetrahydro-1-benzothiophene-3-carboxamide (C20H22N4O2S) 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.
As a certified reference material (CRM), 2-Amino-N-(1,5-dimethyl-3-oxo-2-phenyl-2,3-dihydro-1h-pyrazol-4-yl)-4,5,6,7-tetrahydro-1-benzothiophene-3-carboxamide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
