Chemical Structure

3-(tert-Butyl)-5-methylphenylboronic Acid CAS 193905-93-0 chemical structure

Description

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 3-(tert-Butyl)-5-methylphenylboronic Acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 192.06 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

3-(tert-Butyl)-5-methylphenylboronic Acid (CAS 193905-93-0), molecular formula C11H17BO2 and molecular weight 192.06 g/mol, is a CATO reference standard with documented purity and traceability.

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

As a certified reference material (CRM), 3-(tert-Butyl)-5-methylphenylboronic Acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
