2-[1-(3,5-dimethylphenyl)-2,5-dimethyl-1h-pyrrol-3-yl]acetic acid CAS 42866-02-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-[1-(3,5-dimethylphenyl)-2,5-dimethyl-1h-pyrrol-3-yl]acetic acid.

CATO supplies 2-[1-(3,5-dimethylphenyl)-2,5-dimethyl-1h-pyrrol-3-yl]acetic acid (CAS 42866-02-4), a certified reference material (molecular formula C16H19NO2, MW 257.33 g/mol) for analytical method development and quality control.

The molecular framework of 2-[1-(3,5-dimethylphenyl)-2,5-dimethyl-1h-pyrrol-3-yl]acetic acid (C16H19NO2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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.

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.
