Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 223.61 g/mol gives 2-(4-Chloro-2-nitrophenyl)furan distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2-(4-Chloro-2-nitrophenyl)furan (CAS 88673-90-9), a certified reference material (molecular formula C10H6ClNO3, MW 223.61 g/mol) for analytical method development and quality control.
2-(4-Chloro-2-nitrophenyl)furan (C10H6ClNO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
