2-(3-Chloro-4-fluoro-5-methylphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane CAS 1402238-26-9

Description

Compared with other compounds in its class, the molecular weight of 270.54 g/mol gives 2-(3-Chloro-4-fluoro-5-methylphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-(3-Chloro-4-fluoro-5-methylphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 1402238-26-9) is a high-purity analytical reference standard with the molecular formula C13H17BClFO2 and a molecular weight of 270.54 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system, 2-(3-Chloro-4-fluoro-5-methylphenyl)-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 270.54 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
