5-Borono-4-chloro-2-methoxybenzoic acid CAS 957066-09-0

Description

Compared with other compounds in its class, the molecular weight of 230.41 g/mol gives 5-Borono-4-chloro-2-methoxybenzoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-Borono-4-chloro-2-methoxybenzoic acid (CAS 957066-09-0), molecular formula C8H8BClO5 and molecular weight 230.41 g/mol, is a CATO reference standard with documented purity and traceability.

5-Borono-4-chloro-2-methoxybenzoic acid (C8H8BClO5) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
