ethyl 3-chloroquinoxaline-2-carboxylate; CAS No.: 49679-45-0; ethyl 3-chloroquinoxaline-2-carboxylate. PROPERTIES: Ethyl 3-chloroquinoxaline-2-carboxylate is a crystalline compound with molecular formula C10H8ClN2O2, having a molar mass of approximately 225.63 g/mol. It demonstrates limited water solubility but good solubility in ethyl acetate and methylene chloride. Melting point determinations typically yield values between 72-76 C. Proper storage requires maintaining in airtight containers at temperatures below 30 C, protected from moisture and strong bases. Safety considerations identify it as causing skin irritation and serious eye damage. Precautionary measures recommend using explosion-proof equipment and providing adequate hygiene facilities. APPLICATIONS: This compound serves as a valuable intermediate in the synthesis of antibacterial agents, particularly those targeting multidrug-resistant pathogens. Its chloro substituent at position 3 and ethyl ester at position 2 enable selective alkylation and hydrolysis reactions crucial for constructing target molecules. In agrochemical research (non-agricultural application), it contributes to safener compound development through controlled derivatization pathways. Additionally, the compound supports materials science applications in photostabilizer development for polymer systems, with methodologies published in Journal of Medicinal Chemistry and related pharmaceutical patents, illustrating its significance in antimicrobial therapy and materials protection innovations.
