CATO supplies 4-Amino-2-(3,4-dimethylphenyl)-2,4-dihydro-5-methyl-3H-pyrazol-3-oneDISCONTINUED. Please see A459535. (CAS 2222711-76-2), a certified reference material (molecular formula C12H15N3O, MW 217.27 g/mol) for analytical method development and quality control.
Structurally, 4-Amino-2-(3,4-dimethylphenyl)-2,4-dihydro-5-methyl-3H-pyrazol-3-oneDISCONTINUED. Please see A459535. (C12H15N3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 217.27 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
