Chemical Structure

(E)-2-(2,5-Dimethylstyryl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane CAS 2125491-59-8 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (E)-2-(2,5-Dimethylstyryl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane.

(E)-2-(2,5-Dimethylstyryl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 2125491-59-8) is a high-purity analytical reference standard with the molecular formula C16H23BO2 and a molecular weight of 258.16 g/mol.

(E)-2-(2,5-Dimethylstyryl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (C16H23BO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), (E)-2-(2,5-Dimethylstyryl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane 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.
