Description

The occurrence of 2,5-Dimethyl-1-[4-(propan-2-yl)phenyl]-1h-pyrrole-3-carboxylic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2,5-Dimethyl-1-[4-(propan-2-yl)phenyl]-1h-pyrrole-3-carboxylic acid (CAS 923821-08-3) is a high-purity analytical reference standard with the molecular formula C16H19NO2 and a molecular weight of 257.33 g/mol.

Structurally, 2,5-Dimethyl-1-[4-(propan-2-yl)phenyl]-1h-pyrrole-3-carboxylic acid (C16H19NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 257.33 g/mol, it falls into the medium-molecular-weight range. 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.
