Chemical Structure

1-(1H-PYRAZOL-4-YL)ETHANAMINE CAS 1340143-61-4 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 1-(1H-PYRAZOL-4-YL)ETHANAMINE.

1-(1H-PYRAZOL-4-YL)ETHANAMINE (CAS 1340143-61-4), molecular formula C5H9N3 and molecular weight 111.15 g/mol, is a CATO reference standard with documented purity and traceability.

1-(1H-PYRAZOL-4-YL)ETHANAMINE (C5H9N3) contains a nitrile group. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
