Description

CATO supplies 2-(4-Chloro-2-fluoro-5-isopropoxyphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 1256360-16-3), a certified reference material (molecular formula C15H21BClFO3, MW 314.59 g/mol) for analytical method development and quality control.

Structurally, 2-(4-Chloro-2-fluoro-5-isopropoxyphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (C15H21BClFO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.5, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 314.59 g/mol, it falls into the moderately-high-molecular-weight range. 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
