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 7-Chloro-4-iodo-3-methylisoquinoline (CAS 2073126-57-3), a certified reference material (molecular formula C10H7ClIN, MW 303.53 g/mol) for analytical method development and quality control.
7-Chloro-4-iodo-3-methylisoquinoline (C10H7ClIN) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/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.
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.
