Description

CATO supplies 699-18-3 Furan, 2-(2-nitroethenyl)- (9CI) Furan, 2-(2-nitrovinyl)- 2-(2-Nitrovinyl)furan AI3-18224 CCRIS 5662 Ethylene, 1-(2-furyl)-2-nitro- 1-(alpha-Furyl)-2-nitroethylene 1-(2-Furyl)-2-nitroethylene 2-Furylnitroethylene beta-Nitrovinylfuran NSC 5650 (CAS 699-18-3), a certified reference material (molecular formula C6H9NO3, MW 143.14 g/mol) for analytical method development and quality control.

Based on its molecular formula C6H9NO3, 699-18-3 Furan, 2-(2-nitroethenyl)- (9CI) Furan, 2-(2-nitrovinyl)- 2-(2-Nitrovinyl)furan AI3-18224 CCRIS 5662 Ethylene, 1-(2-furyl)-2-nitro- 1-(alpha-Furyl)-2-nitroethylene 1-(2-Furyl)-2-nitroethylene 2-Furylnitroethylene beta-Nitrovinylfuran NSC 5650 contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 143.14 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
