2-(3′,5′-Difluoro[1,1′-biphenyl]-4-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane CAS 2250042-17-0

Description

Owing to a steroid core, a hydroxyl group, an ether linkage, fluorine substitution, 2-(3′,5′-Difluoro[1,1′-biphenyl]-4-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 316.15 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.

2-(3′,5′-Difluoro[1,1′-biphenyl]-4-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 2250042-17-0), molecular formula C18H19BF2O2 and molecular weight 316.15 g/mol, is a CATO reference standard with documented purity and traceability.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
