Description

1,4-Benzodioxin-6-Carbonyl Chloride, 2,3-Dihydro-5-Methyl- (9Ci) is a specialized organic intermediate featuring a benzodioxane core activated by a reactive carbonyl chloride (acid chloride) group. This compound matters as a critical building block for synthesizing more complex molecules, enabling the introduction of the 1,4-benzodioxin moiety into target structures. It is primarily needed by research chemists and process development scientists in the pharmaceutical and agrochemical industries for creating novel active ingredients and fine chemicals.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of potential drug candidates, particularly those targeting neurological or cardiovascular pathways where the benzodioxane scaffold is pharmacologically relevant.
• Agrochemical Synthesis: Used in the research and development of new herbicides, fungicides, or insecticides, leveraging its heterocyclic structure.
• Material Science Research: Serves as a monomer or functionalization agent in the development of advanced polymers and specialty materials with specific optical or electronic properties.
• Chemical Biology Probes: Employed to create molecular probes and tags for studying biological systems and enzyme activity.
• Custom Synthesis & Contract Manufacturing: A vital starting material for custom synthesis houses and CDMOs (Contract Development and Manufacturing Organizations) producing bespoke compounds for client projects.

Quality Control

Our 1,4-Benzodioxin-6-Carbonyl Chloride, 2,3-Dihydro-5-Methyl- (9Ci) is produced under strict quality management protocols. Every batch undergoes comprehensive analytical testing, including HPLC, NMR, and IR spectroscopy, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all test results are available upon request to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its nature as a strong acid/organic solvent derivative, it should be kept away from moisture, strong bases, and oxidizing agents. Use appropriate corrosion-resistant storage materials.
