Description
CATO manufactures (1-Naphthylmethyl)boronic acid pinacol ester, 97% 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 (1-Naphthylmethyl)boronic acid pinacol ester, 97% (CAS 475250-57-8), a certified reference material (molecular formula C17H21BO2, MW 268.16 g/mol) for analytical method development and quality control.
The molecular framework of (1-Naphthylmethyl)boronic acid pinacol ester, 97% (C17H21BO2) is characterized by a steroid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
