Description
As a certified reference material (CRM), 2,4-Dichloro-7-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.
2,4-Dichloro-7-methylquinoline (CAS 102878-19-3) is a high-purity analytical reference standard with the molecular formula C10H7Cl2N and a molecular weight of 212.08 g/mol.
2,4-Dichloro-7-methylquinoline (C10H7Cl2N) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
