Chemical Structure
Description
CATO supplies Ethyl 8-chloro-2-(ethylthio)-4-hydroxyquinoline-3-carboxylate (CAS 861397-35-5), a certified reference material (molecular formula C14H14ClNO3S, MW 311.78 g/mol) for analytical method development and quality control.
Structurally, Ethyl 8-chloro-2-(ethylthio)-4-hydroxyquinoline-3-carboxylate (C14H14ClNO3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 311.78 g/mol, it falls into the moderately-high-molecular-weight range. 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.
