Chemical Structure
Description
The occurrence of (4-Methoxy-3-(methoxycarbonyl)phenyl)boronic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(4-Methoxy-3-(methoxycarbonyl)phenyl)boronic acid (CAS 1071958-96-7), molecular formula C9H11BO5 and molecular weight 209.99 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (4-Methoxy-3-(methoxycarbonyl)phenyl)boronic acid (C9H11BO5) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.5, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 209.99 g/mol, it falls into the medium-molecular-weight range. 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-Methoxy-3-(methoxycarbonyl)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.
