Diethyl ethoxymethylenemalonate Cas 87-13-8

Pharmaceutical Intermediates: Key raw materials for the synthesis of quinolone antibiotics, serving as the building blocks for constructing the quinoline ring core. Used in the synthesis of Vitamin B1, folic acid, pyrimidine- and purine-based drugs, as well as heterocyclic anti-tuberculosis, antiviral, and anti-tumor medications.
Organic Synthesis Building Blocks: Utilized for constructing heterocyclic compounds such as pyrimidines, quinolines, isoquinolines, pyrazoles, triazoles, and coumarins; capable of undergoing condensation and cyclization reactions with amines, hydrazines, and amidines.
Dyes and Fine Chemicals: Intermediates for the synthesis of fluorescent dyes, heterocyclic organic pigments, photosensitizers, and optoelectronic materials.
Agrochemical Intermediates: Raw materials providing the heterocyclic structural scaffolds for the preparation of herbicides, fungicides, and plant growth regulators.
