Description

Uracil CAS NO 66-22-8 is a naturally occurring pyrimidine nucleobase fundamental to RNA structure and function. Its primary commercial value lies in its role as a key building block for the synthesis of pharmaceuticals, agrochemicals, and biochemical research reagents. This high-purity compound is essential for manufacturers and research institutions in the pharmaceutical, agrochemical, and life science sectors requiring a reliable and consistent raw material for nucleoside and nucleotide production.

Application

• Pharmaceutical Intermediate: A critical precursor in the synthesis of antiviral and anticancer drugs, such as 5-fluorouracil and related nucleoside analogs.
• Agrochemical Synthesis: Used in the production of certain herbicides and plant growth regulators that target pyrimidine metabolism.
• Biochemical Research: Serves as a standard and reagent in molecular biology, genetics, and metabolic pathway studies.
• Nucleoside/Nucleotide Manufacturing: A core starting material for the industrial-scale production of uridine and its phosphorylated derivatives.
• Cosmetic & Personal Care: Incorporated into specific formulations for its potential skin-conditioning properties.
• Food & Feed Additive Precursor: Used in the synthesis of certain nutritional supplements and feed additives.
