4-Isopropyl-1-(2-methoxyphenyl)-7-(methylthio)-1H-pyrazolo[3,4-d]pyridazine CAS 1105204-83-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Isopropyl-1-(2-methoxyphenyl)-7-(methylthio)-1H-pyrazolo[3,4-d]pyridazine.

CATO supplies 4-Isopropyl-1-(2-methoxyphenyl)-7-(methylthio)-1H-pyrazolo[3,4-d]pyridazine (CAS 1105204-83-8), a certified reference material (molecular formula C16H18N4OS, MW 314.41 g/mol) for analytical method development and quality control.

The molecular framework of 4-Isopropyl-1-(2-methoxyphenyl)-7-(methylthio)-1H-pyrazolo[3,4-d]pyridazine (C16H18N4OS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
