Chemical Structure
Description
CATO supplies 1-(4-(((5-methyl-1-phenyl-1H-pyrazol-4-yl)methyl)amino)phenyl)butan-1-one (CAS 1091670-41-5), a certified reference material (molecular formula C21H23N3O, MW 333.43 g/mol) for analytical method development and quality control.
Structurally, 1-(4-(((5-methyl-1-phenyl-1H-pyrazol-4-yl)methyl)amino)phenyl)butan-1-one (C21H23N3O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 333.43 g/mol, it falls into the moderately-high-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.
