Description
Compared with other compounds in its class, the molecular weight of 188.03 g/mol gives (3-(Cyclopent-1-en-1-yl)phenyl)boronic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(3-(Cyclopent-1-en-1-yl)phenyl)boronic acid (CAS 1256345-86-4) is a high-purity analytical reference standard with the molecular formula C11H13BO2 and a molecular weight of 188.03 g/mol.
(3-(Cyclopent-1-en-1-yl)phenyl)boronic acid (C11H13BO2) 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 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures (3-(Cyclopent-1-en-1-yl)phenyl)boronic acid 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.
