Chemical Structure
Description
The occurrence of (3-Ethyl-5-methylphenyl)boronic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies (3-Ethyl-5-methylphenyl)boronic acid (CAS 2426630-87-5), a certified reference material (molecular formula C9H13BO2, MW 164.01 g/mol) for analytical method development and quality control.
Based on its molecular formula C9H13BO2, (3-Ethyl-5-methylphenyl)boronic acid contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 164.01 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), (3-Ethyl-5-methylphenyl)boronic 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.
