Overview

3-O-ethyl 5-O-methyl 2-(2-aminoethoxymethyl)-4-(2-chlorophenyl)-6-methyl-1,4-dihydropyridine-3,5-dicarboxylate (CAS 88150-42-9) is a dihydropyridine derivative with calcium channel blocking properties and complex molecular architecture. This pharmaceutical intermediate belongs to the dihydropyridine class of compounds, characterized by its distinctive 1,4-dihydropyridine ring system substituted with ethyl and methyl carboxylate groups. The molecular structure features a 2-chlorophenyl substituent at position 4 and an aminoethoxymethyl side chain, contributing to its molecular weight of 408.9 g/mol and formula C20H25ClN2O5. The compound exhibits significant biological activity due to its structural similarity to known calcium channel antagonists. From a safety perspective, this substance requires careful handling protocols due to its classification under multiple hazard categories. The compound presents acute toxicity concerns (Acute Tox. 3), potential for serious eye damage (Eye Dam. 1), and specific target organ toxicity with repeated exposure (STOT RE 2). Environmental considerations are equally important, as it demonstrates both acute and chronic aquatic toxicity. The GHS06, GHS08, GHS05, and GHS09 pictograms reflect these diverse hazard profiles, necessitating appropriate personal protective equipment and containment measures during handling and storage. Industrial applications typically center around pharmaceutical research and development, particularly in cardiovascular drug synthesis and calcium channel blocker research programs. The compound also serves as a valuable synthetic intermediate for developing novel therapeutic agents with enhanced selectivity profiles. Unlike simpler compounds such as 1-chloro-4-isocyanatobenzene, this complex dihydropyridine requires specialized synthetic approaches and purification techniques. OYSI maintains reliable supply chains for this specialized pharmaceutical intermediate, supporting research institutions and pharmaceutical companies across Europe with consistent quality and regulatory compliance.
