CAS 99-27-4: 1,3-Benzenedicarboxylic acid, 5-amino-, 1,3-dimethyl ester

Dimethyl 5-aminoisophthalate is a important organic intermediate. It can be used in agrochemical, pharmaceutical and dyestuff field. Hexagonal assembly of double helices of luminescent calcium 5-aminoisophthalate coordination polymer leaves enough room for the formation of loosely held water pipes, which could be dehydrated at very low temperatures. This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Dimethyl 5-aminoisophthalate

Dimethyl 5-aminoisophthalate (5AIM) is a homogeneous catalyst that has shown efficient reactions for the synthesis of 1,4-dihydropyridines. The crystalline structure of 5AIM was determined by x-ray diffraction and exhibits two distinct conformations depending on the solvent. It can be synthesized from methyl aminomalonate and ethylene glycol in a one-pot reaction. The hydrochloric acid-catalyzed hydrolysis of sodium taurocholate provides the hydroxyl group required for 5AIM synthesis. Molecular modelling studies have suggested that the diphosphine ligand may be involved in metal ion catalysis, but this has not been confirmed experimentally. Magnetic resonance spectroscopy studies have shown that model complexes containing 5AIM are stable at room temperature and pressure conditions.
