2-(5-Chloro-2-fluorophenyl)-5,5-dimethyl-1,3,2-dioxaborinane CAS 628692-19-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(5-Chloro-2-fluorophenyl)-5,5-dimethyl-1,3,2-dioxaborinane.

2-(5-Chloro-2-fluorophenyl)-5,5-dimethyl-1,3,2-dioxaborinane (CAS 628692-19-3), molecular formula C11H13BClFO2 and molecular weight 242.48 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system, 2-(5-Chloro-2-fluorophenyl)-5,5-dimethyl-1,3,2-dioxaborinane is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 242.48 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.
