Description

2,4-Dichloro-5-Ethylpyrimidine is a versatile halogenated pyrimidine building block of significant importance in advanced organic synthesis. Its core value lies in its dual reactive sites, which enable selective functionalization for constructing complex heterocyclic systems. This intermediate is primarily needed by research and development chemists and process engineers in the pharmaceutical and agrochemical industries for the development of active ingredients and novel compounds.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for antiviral, anticancer, and kinase inhibitor drugs.
• Agrochemical Synthesis: Used in the manufacture of herbicides, fungicides, and plant growth regulators where the pyrimidine core is a critical structural motif.
• Material Science Research: Serves as a building block for creating novel organic electronic materials, ligands for metal-organic frameworks (MOFs), and liquid crystals.
• Custom Synthesis & Contract Manufacturing: Employed by fine chemical companies for bespoke synthesis projects and scale-up processes for client-specific molecules.
• Academic & Industrial R&D: Utilized in research laboratories for method development, exploring new reaction pathways, and creating libraries of compounds for screening.

Quality Control

Our 2,4-Dichloro-5-Ethylpyrimidine is produced under strict quality management protocols. Every batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistency. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided and available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent degradation from atmospheric moisture.
