Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 143.19 g/mol gives 5-methylquinoline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 5-methylquinoline (CAS 7661-55-4), a certified reference material (molecular formula C10H9N, MW 143.19 g/mol) for analytical method development and quality control.
5-methylquinoline (C10H9N) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. 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.
As a certified reference material (CRM), 5-methylquinoline meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
