Description
CATO supplies 3-(5,6-Dihydro-4h-cyclopenta[b]thiophen-2-yl)-1-methyl-1h-pyrazol-5-amine (CAS 1152649-44-9), a certified reference material (molecular formula C11H13N3S, MW 219.31 g/mol) for analytical method development and quality control.
The molecular framework of 3-(5,6-Dihydro-4h-cyclopenta[b]thiophen-2-yl)-1-methyl-1h-pyrazol-5-amine (C11H13N3S) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 3-(5,6-Dihydro-4h-cyclopenta[b]thiophen-2-yl)-1-methyl-1h-pyrazol-5-amine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
