5-(tert-Butoxycarbonyl)-4-chloro-2-fluorophenylboronic Acid Pinacol Ester CAS 1218789-89-9

Description

Structurally, 5-(tert-Butoxycarbonyl)-4-chloro-2-fluorophenylboronic Acid Pinacol Ester (C17H23BClFO4) contains a steroid core, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 5.5, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 356.62 g/mol, it falls into the moderately-high-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.

5-(tert-Butoxycarbonyl)-4-chloro-2-fluorophenylboronic Acid Pinacol Ester (CAS 1218789-89-9) is a high-purity analytical reference standard with the molecular formula C17H23BClFO4 and a molecular weight of 356.62 g/mol.

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.
