Description
As a certified reference material (CRM), 2-Chloro-3-(hydrazonomethyl)-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-Chloro-3-(hydrazonomethyl)-7-methylquinoline (CAS 80231-53-4), molecular formula C11H10ClN3 and molecular weight 219.67 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 2-Chloro-3-(hydrazonomethyl)-7-methylquinoline is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 219.67 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
