6-Chloro-2,5-dimethylpyridazin-3(2H)-one CAS 1114563-59-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6-Chloro-2,5-dimethylpyridazin-3(2H)-one.

6-Chloro-2,5-dimethylpyridazin-3(2H)-one (CAS 1114563-59-5), molecular formula C6H7ClN2O and molecular weight 158.59 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C6H7ClN2O, 6-Chloro-2,5-dimethylpyridazin-3(2H)-one contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 158.59 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

As a certified reference material (CRM), 6-Chloro-2,5-dimethylpyridazin-3(2H)-one 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.
