Chemical Structure
Description
The molecular framework of 7-(Ethylthio)-1-(4-fluorophenyl)-4-methyl-1H-pyrazolo[3,4-d]pyridazine (C14H13FN4S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
7-(Ethylthio)-1-(4-fluorophenyl)-4-methyl-1H-pyrazolo[3,4-d]pyridazine (CAS 1105236-38-1) is a high-purity analytical reference standard with the molecular formula C14H13FN4S and a molecular weight of 288.34 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
