Chemical Structure
Description
CATO supplies 2-(5-Fluorobenzofuran-2-yl)acetonitrile (CAS 139313-91-0), a certified reference material (molecular formula C10H6FNO, MW 175.16 g/mol) for analytical method development and quality control.
Based on its molecular formula C10H6FNO, 2-(5-Fluorobenzofuran-2-yl)acetonitrile contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 175.16 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.
