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 5-tert-Butyl-2-phenyl-2H-pyrazol-3-ylamin.
5-tert-Butyl-2-phenyl-2H-pyrazol-3-ylamin (CAS 126208-61-5) is a high-purity analytical reference standard with the molecular formula C13H17N3 and a molecular weight of 215.29 g/mol.
The molecular framework of 5-tert-Butyl-2-phenyl-2H-pyrazol-3-ylamin (C13H17N3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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. 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.
