Chemical Structure
Description
(5-METHYL-4,5-DIHYDRO-1H-PYRAZOL-1-YL)(PYRIDIN-3-YL)METHANONE (CAS 121306-58-9) is a high-purity analytical reference standard with the molecular formula C10H11N3O and a molecular weight of 189.21 g/mol.
Structurally, (5-METHYL-4,5-DIHYDRO-1H-PYRAZOL-1-YL)(PYRIDIN-3-YL)METHANONE (C10H11N3O) 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 189.21 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
