3-(4-Ethoxyphenyl)-7-phenylhexahydro-1H-pyridazino[1,2-a][1,2,5]triazepine-1,5(2H)-dione CAS 67744-85-8 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(4-Ethoxyphenyl)-7-phenylhexahydro-1H-pyridazino[1,2-a][1,2,5]triazepine-1,5(2H)-dione.

3-(4-Ethoxyphenyl)-7-phenylhexahydro-1H-pyridazino[1,2-a][1,2,5]triazepine-1,5(2H)-dione (CAS 67744-85-8), molecular formula C22H25N3O3 and molecular weight 379.45 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-(4-Ethoxyphenyl)-7-phenylhexahydro-1H-pyridazino[1,2-a][1,2,5]triazepine-1,5(2H)-dione (C22H25N3O3) is characterized by a steroid core, an amide 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
