Chemical Structure
Description
4-Chloro-3-isopropoxyphenylboronic Acid (CAS 1256346-35-6), molecular formula C9H12BClO3 and molecular weight 214.45 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C9H12BClO3, 4-Chloro-3-isopropoxyphenylboronic Acid contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 214.45 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
As a certified reference material (CRM), 4-Chloro-3-isopropoxyphenylboronic 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.
