Chemical Structure
Description
The occurrence of 2-Chloro-3-iodo-4-methoxypyridine is closely related to an amide group, a hydroxyl group, an ether linkage, chlorine/iodine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2-Chloro-3-iodo-4-methoxypyridine (CAS 1163693-01-3), a certified reference material (molecular formula C6H5ClINO, MW 269.47 g/mol) for analytical method development and quality control.
2-Chloro-3-iodo-4-methoxypyridine (C6H5ClINO) contains an amide group, a hydroxyl group, an ether linkage, chlorine/iodine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
