Chemical Structure

1-(2-Phenylethyl)-1h-pyrazol-3-amine CAS 876343-25-8 chemical structure

Description

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.

1-(2-Phenylethyl)-1h-pyrazol-3-amine (CAS 876343-25-8) is a high-purity analytical reference standard with the molecular formula C11H13N3 and a molecular weight of 187.24 g/mol.

The molecular framework of 1-(2-Phenylethyl)-1h-pyrazol-3-amine (C11H13N3) 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.

As a certified reference material (CRM), 1-(2-Phenylethyl)-1h-pyrazol-3-amine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
