3-Hydroxy-6-chloropyridazine as a Key Intermediate for Agrochemical Lead Compound Synthesis

3-Hydroxy-6-chloropyridazine

Product: 3-Hydroxy-6-chloropyridazine
Client Background: The China R&D Center of a multinational agrochemical corporation.
Project Requirements:

  • To serve as an intermediate for novel insecticide scaffold design, requiring high reactivity of the halogen-containing heterocycle.
  • Strict control of moisture, halogenated impurities, and metal ion residues across batches.

Wealsun’s Solution:

  • Implemented anhydrous system operations during scale-up synthesis to ensure precise control of chlorine content.
  • Provided complete Certificate of Analysis (COA) and ICP-MS reports for metal impurity verification.

Outcomes:

  • After confirming material compliance, the client contract the development of multiple analogous pyridazine-based compounds.
  • A long-term joint development collaboration was established between both parties.

FAQ

What are pharmaceutical chemicals used for?

Pharmaceutical chemicals are used primarlyin the development,formulation,and production ofmedications. Theyinclude active ingredient,excipients,intermediates, and
other substances that ensure the drug’s effectiveness, stabilitv, and safety.

A: Pharmaceutical chemicals are specifically designed and manufactured to meet stringent purity, safety, and quality standards required in drug production. They undergo rigorous testing and comply with global regulations, unlike general chemical products which may not meet such high standards.

A: Active Pharmaceutical Ingredients (APIs) are the main components responsible for the therapeutic effects of a drug. They directly target the medical condition being treated, making them crucial in every medication.

A: Pharmaceutical intermediates are precursor compounds used in the synthesis of APIs. They are essential steps in the multi-stage production process of complex pharmaceutical compounds.

A: Excipients are inactive substances that enhance drug formulation by acting as carriers, stabilizers, or binders. They help in the proper delivery, absorption, and shelf life of the medication.
