1,1-Difluoro-1-Nitro-2-Butanone CAS 33128-11-9

Description

Compared with other compounds in its class, the molecular weight of 153.08 g/mol gives 1,1-Difluoro-1-Nitro-2-Butanone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 1,1-Difluoro-1-Nitro-2-Butanone (CAS 33128-11-9), a certified reference material (molecular formula C4H5F2NO3, MW 153.08 g/mol) for analytical method development and quality control.

1,1-Difluoro-1-Nitro-2-Butanone (C4H5F2NO3) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
