Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7-Iodo-4-methylquinoline.
7-Iodo-4-methylquinoline (CAS 144147-02-4), molecular formula C10H8IN and molecular weight 269.08 g/mol, is a CATO reference standard with documented purity and traceability.
7-Iodo-4-methylquinoline (C10H8IN) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, iodine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
