5-Fluoro-2-nitrobenzoyl chloride, 98% CAS 394-02-5

Description

The occurrence of 5-Fluoro-2-nitrobenzoyl chloride, 98% is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-Fluoro-2-nitrobenzoyl chloride, 98% (CAS 394-02-5) is a high-purity analytical reference standard with the molecular formula C7H3ClFNO3 and a molecular weight of 203.56 g/mol.

5-Fluoro-2-nitrobenzoyl chloride, 98% (C7H3ClFNO3) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/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.
