[4-(2-Methoxyethyl)phenyl]boronic acid CAS 188479-23-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including [4-(2-Methoxyethyl)phenyl]boronic acid.

[4-(2-Methoxyethyl)phenyl]boronic acid (CAS 188479-23-4), molecular formula C9H13BO3 and molecular weight 180.01 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, [4-(2-Methoxyethyl)phenyl]boronic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 180.01 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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-(2-Methoxyethyl)phenyl]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.
