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-(3,4-Dimethylphenyl)-2,5-dimethyl-1h-pyrrole-3-carboxylic acid.
1-(3,4-Dimethylphenyl)-2,5-dimethyl-1h-pyrrole-3-carboxylic acid (CAS 923717-97-9) is a high-purity analytical reference standard with the molecular formula C15H17NO2 and a molecular weight of 243.30 g/mol.
The molecular framework of 1-(3,4-Dimethylphenyl)-2,5-dimethyl-1h-pyrrole-3-carboxylic acid (C15H17NO2) 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
