Chemical Structure
Description
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.
CATO supplies 7-Chloro-2,2,4-trimethyl-1,2-dihydroquinoline (CAS 1810-73-7), a certified reference material (molecular formula C12H14ClN, MW 207.70 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 7-Chloro-2,2,4-trimethyl-1,2-dihydroquinoline is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 207.70 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
