The journey from basic research to a finished pharmaceutical product often relies on a series of complex chemical transformations. Central to this process are chemical intermediates – compounds that serve as building blocks for synthesizing Active Pharmaceutical Ingredients (APIs). Methyl 4,6-dichloropyridazine-3-carboxylate (CAS: 372118-01-9) is a notable example, recognized for its utility in constructing diverse molecular structures essential for modern medicine. For professionals in the pharmaceutical industry looking to buy this compound, understanding its synthesis, applications, and sourcing from reputable manufacturers is key.

Synthesis and Chemical Properties
Methyl 4,6-dichloropyridazine-3-carboxylate is a derivative of pyridazine, a six-membered heterocyclic aromatic ring containing two adjacent nitrogen atoms. Its synthesis typically involves the chlorination of a precursor molecule, such as a hydroxypyridazine carboxylate. For instance, a common route involves reacting methyl 4,6-dihydroxypyridazine-3-carboxylate with phosphoryl chloride or phosphorus trichloride under controlled conditions. The resulting compound features two reactive chlorine atoms and a methyl ester group, making it highly versatile for further chemical modifications. Its physical properties, often described as a light beige to light brown crystalline powder with a high boiling point, dictate specific handling and storage requirements, such as maintaining it under an inert atmosphere and at freezer temperatures (-20°C) to preserve its integrity.

Applications in Pharmaceutical Synthesis
The primary application of Methyl 4,6-dichloropyridazine-3-carboxylate lies in its role as a crucial intermediate in the synthesis of various APIs. The two chlorine atoms on the pyridazine ring are excellent leaving groups, readily undergoing nucleophilic substitution reactions. This allows chemists to introduce a wide array of functional groups, building up the complex molecular structures required for therapeutic compounds. It has been identified as an intermediate in the synthesis pathways for drugs targeting various diseases, including cancer and inflammatory conditions. The compound's specific structure makes it an ideal starting point for creating novel heterocyclic scaffolds that are prevalent in many modern pharmaceuticals. Researchers often procure this intermediate for its potential in drug discovery pipelines.

Sourcing and Quality Assurance
For organizations that need to purchase Methyl 4,6-dichloropyridazine-3-carboxylate, sourcing from reliable manufacturers is paramount. Companies specializing in fine chemical intermediates, particularly those based in China, often offer high-quality products with guaranteed purity (typically 97% min). These manufacturers, such as NINGBO INNO PHARMCHEM CO.,LTD., provide essential documentation like Certificates of Analysis (CoA) and Safety Data Sheets (SDS), ensuring that the product meets stringent quality standards. When you search for 'buy Methyl 4,6-dichloropyridazine-3-carboxylate,' prioritize suppliers who can demonstrate consistent quality, competitive pricing, and reliable delivery. Their expertise in chemical synthesis and quality control is vital for pharmaceutical applications.
