Chemical Structure
Description
The occurrence of ((1R,2R)-2-phenylcyclopropyl)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.
((1R,2R)-2-phenylcyclopropyl)boronic acid (CAS 217634-41-8), molecular formula C9H11BO2 and molecular weight 161.99 g/mol, is a CATO reference standard with documented purity and traceability.
((1R,2R)-2-phenylcyclopropyl)boronic acid (C9H11BO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), ((1R,2R)-2-phenylcyclopropyl)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.
