Chemical Structure
Description
The molecular framework of 3-(Benzo[b]thiophen-3-yl)-1-methyl-1h-pyrazol-5-amine (C12H11N3S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO supplies 3-(Benzo[b]thiophen-3-yl)-1-methyl-1h-pyrazol-5-amine (CAS 1249345-15-0), a certified reference material (molecular formula C12H11N3S, MW 229.30 g/mol) for analytical method development and quality control.
