(1-Methyl-5-((5-(4-methylpiperazin-1-yl)pyridin-2-yl)amino)-6-oxo-1,6-dihydropyridin-3-yl)boronic acid pinacol ester, 97% (CAS 1242156-62-2), molecular formula C22H32BN5O3 and molecular weight 425.33 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (1-Methyl-5-((5-(4-methylpiperazin-1-yl)pyridin-2-yl)amino)-6-oxo-1,6-dihydropyridin-3-yl)boronic acid pinacol ester, 97% (C22H32BN5O3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
