Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(4-Methoxyphenyl)-3-(o-tolyl)-1H-pyrazol-5-amine.
CATO supplies 1-(4-Methoxyphenyl)-3-(o-tolyl)-1H-pyrazol-5-amine (CAS 618098-11-6), a certified reference material (molecular formula C17H17N3O, MW 279.34 g/mol) for analytical method development and quality control.
1-(4-Methoxyphenyl)-3-(o-tolyl)-1H-pyrazol-5-amine (C17H17N3O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
