Chemical Structure
Description
4-(tert-Butyl)-1H-pyrazol-3-amine (CAS 255047-12-2) is a high-purity analytical reference standard with the molecular formula C7H13N3 and a molecular weight of 139.20 g/mol.
The molecular framework of 4-(tert-Butyl)-1H-pyrazol-3-amine (C7H13N3) is characterized by a nitrile group. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
