Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies (4-(1H-pyrazol-1-yl)thiophen-2-yl)boronic acid (CAS 2225155-77-9), a certified reference material (molecular formula C7H7BN2O2S, MW 194.02 g/mol) for analytical method development and quality control.
The molecular framework of (4-(1H-pyrazol-1-yl)thiophen-2-yl)boronic acid (C7H7BN2O2S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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 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).
CATO manufactures (4-(1H-pyrazol-1-yl)thiophen-2-yl)boronic acid 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.
