Chemical Structure
Description
The molecular framework of (3-Chloro-4-((tetrahydro-2H-pyran-4-yl)oxy)phenyl)boronic acid pinacol ester, 97% (C17H24BClO4) is characterized by a steroid core, a hydroxyl group, an ether linkage, chlorine substitution. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
(3-Chloro-4-((tetrahydro-2H-pyran-4-yl)oxy)phenyl)boronic acid pinacol ester, 97% (CAS 1056465-09-8), molecular formula C17H24BClO4 and molecular weight 338.63 g/mol, is a CATO reference standard with documented purity and traceability.
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), (3-Chloro-4-((tetrahydro-2H-pyran-4-yl)oxy)phenyl)boronic acid pinacol ester, 97% 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.
