Chemical Structure

3-amino-3-(1-phenyl-1H-pyrazol-4-yl)propanoic acid CAS 21936-99-2 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 3-amino-3-(1-phenyl-1H-pyrazol-4-yl)propanoic acid.

CATO supplies 3-amino-3-(1-phenyl-1H-pyrazol-4-yl)propanoic acid (CAS 21936-99-2), a certified reference material (molecular formula C12H13N3O2, MW 231.25 g/mol) for analytical method development and quality control.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 3-amino-3-(1-phenyl-1H-pyrazol-4-yl)propanoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 231.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
