Description

4-Amino-1-Methyl-5,6-Dihydropyrimidin-2(1H)-One Hydrochloride is a high-purity, heterocyclic organic compound primarily used as a critical pharmaceutical intermediate. This compound matters because it serves as a versatile building block in the synthesis of complex active pharmaceutical ingredients (APIs), particularly in antiviral and anticancer research. It is essential for B2B buyers in the pharmaceutical, agrochemical, and fine chemical industries who require reliable, high-quality raw materials for research, development, and production.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of nucleoside analogs and other antiviral or anticancer drug candidates.
• Agrochemical Research: Used in the development of novel pesticides and herbicides due to its heterocyclic pyrimidine core.
• Fine Chemical Synthesis: Serves as a precursor for more complex heterocyclic compounds in specialty chemical manufacturing.
• Biochemical Research: Utilized in academic and industrial R&D for studying enzyme inhibitors and metabolic pathways.
• Material Science: Potential monomer or additive in the development of advanced polymeric materials.

Quality Control

Our 4-Amino-1-Methyl-5,6-Dihydropyrimidin-2(1H)-One Hydrochloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for pharmaceutical intermediate applications. Certificates of Analysis (COA) documenting purity, assay, and impurity profiles are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed to prevent degradation from atmospheric moisture.
