Chemical Structure

(E)-2-(2-Cyclopentylvinyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane CAS 157945-82-9 chemical structure

Description

(E)-2-(2-Cyclopentylvinyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 157945-82-9), molecular formula C13H23BO2 and molecular weight 222.13 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, (E)-2-(2-Cyclopentylvinyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 222.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

CATO manufactures (E)-2-(2-Cyclopentylvinyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
