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 (5-Formyl-1H-pyrrol-2-yl)boronic acid (CAS 1021342-99-3), a certified reference material (molecular formula C5H6BNO3, MW 138.92 g/mol) for analytical method development and quality control.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, (5-Formyl-1H-pyrrol-2-yl)boronic acid is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 138.92 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 (5-Formyl-1H-pyrrol-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.
