Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 5-Chloro-N-(2,6-difluorophenyl)pyrazine-2-carboxamide (CAS 1373940-69-2), a certified reference material (molecular formula C11H6ClF2N3O, MW 269.63 g/mol) for analytical method development and quality control.
Structurally, 5-Chloro-N-(2,6-difluorophenyl)pyrazine-2-carboxamide (C11H6ClF2N3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 269.63 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
