6-(3,4-Dimethylphenyl)pyridazin-3-ol CAS 4826-91-9

Description

The occurrence of 6-(3,4-Dimethylphenyl)pyridazin-3-ol is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

6-(3,4-Dimethylphenyl)pyridazin-3-ol (CAS 4826-91-9), molecular formula C12H12N2O and molecular weight 200.24 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C12H12N2O, 6-(3,4-Dimethylphenyl)pyridazin-3-ol contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 200.24 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
