Chemical Structure

3-(tert-Butyl)-1-(4-methoxyphenyl)-1H-pyrazol-5-amine CAS 227623-26-9 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies 3-(tert-Butyl)-1-(4-methoxyphenyl)-1H-pyrazol-5-amine (CAS 227623-26-9), a certified reference material (molecular formula C14H19N3O, MW 245.32 g/mol) for analytical method development and quality control.

The molecular framework of 3-(tert-Butyl)-1-(4-methoxyphenyl)-1H-pyrazol-5-amine (C14H19N3O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
