Chemical Structure
Description
The occurrence of 1-(2-(3,5-Dimethyl-1H-pyrazol-1-yl)ethyl)-3-(4-fluorobenzyl)urea is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-(2-(3,5-Dimethyl-1H-pyrazol-1-yl)ethyl)-3-(4-fluorobenzyl)urea (CAS 1226441-58-2), molecular formula C15H19FN4O and molecular weight 290.34 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-(2-(3,5-Dimethyl-1H-pyrazol-1-yl)ethyl)-3-(4-fluorobenzyl)urea (C15H19FN4O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 290.34 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
