Chemical Structure

1-BOC-4-(methylcarbonyl)indole-3-boronic acid, pinacol ester CAS 1256359-97-3 chemical structure

Description

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.

1-BOC-4-(methylcarbonyl)indole-3-boronic acid, pinacol ester (CAS 1256359-97-3), molecular formula C21H28BNO6 and molecular weight 401.26 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1-BOC-4-(methylcarbonyl)indole-3-boronic acid, pinacol ester (C21H28BNO6) is characterized by a flavonoid 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
