Chemical Structure

1,3-Di-tert-Butyl-1H-pyrazol-5-amine CAS 787552-38-9 chemical structure

Description

CATO supplies 1,3-Di-tert-Butyl-1H-pyrazol-5-amine (CAS 787552-38-9), a certified reference material (molecular formula C11H21N3, MW 195.30 g/mol) for analytical method development and quality control.

Based on its molecular formula C11H21N3, 1,3-Di-tert-Butyl-1H-pyrazol-5-amine contains a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 195.30 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
