Chemical Structure

1-(3,4-DIchlorophenyl)-5-(3,4-dimethylphenyl)-2-methyl-1h-pyrrole-3-carboxylic acid CAS 881041-33-4 chemical structure

Description

1-(3,4-DIchlorophenyl)-5-(3,4-dimethylphenyl)-2-methyl-1h-pyrrole-3-carboxylic acid (C20H17Cl2NO2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).

1-(3,4-DIchlorophenyl)-5-(3,4-dimethylphenyl)-2-methyl-1h-pyrrole-3-carboxylic acid (CAS 881041-33-4) is a high-purity analytical reference standard with the molecular formula C20H17Cl2NO2 and a molecular weight of 374.26 g/mol.
