2-(4-(4,4-Difluorocyclohexyl)phenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane CAS 2648450-81-9

Description

2-(4-(4,4-Difluorocyclohexyl)phenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 2648450-81-9) is a high-purity analytical reference standard with the molecular formula C18H25BF2O2 and a molecular weight of 322.20 g/mol.

Owing to a steroid core, a hydroxyl group, an ether linkage, fluorine substitution, 2-(4-(4,4-Difluorocyclohexyl)phenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 322.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

As a certified reference material (CRM), 2-(4-(4,4-Difluorocyclohexyl)phenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane 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.
