Description
As a certified reference material (CRM), 2-Chloro-7-methoxyquinoline-3-carbonitrile 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-Chloro-7-methoxyquinoline-3-carbonitrile (CAS 128259-63-2) is a high-purity analytical reference standard with the molecular formula C11H17ClN2O and a molecular weight of 228.72 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 2-Chloro-7-methoxyquinoline-3-carbonitrile is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 228.72 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
