Chemical Structure

3,5-Diphenylphenylboronic Acid CAS 128388-54-5 chemical structure

Description

CATO manufactures 3,5-Diphenylphenylboronic 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.

CATO supplies 3,5-Diphenylphenylboronic Acid (CAS 128388-54-5), a certified reference material (molecular formula C18H15BO2, MW 274.12 g/mol) for analytical method development and quality control.

Structurally, 3,5-Diphenylphenylboronic Acid (C18H15BO2) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 11.5, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 274.12 g/mol, it falls into the medium-molecular-weight range. 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.
