Description

1-Azulenecarbonyl Chloride, 3-Methyl- (9Ci) is a specialized organic reagent featuring a reactive acid chloride group on the unique azulene core. This compound matters as a key building block for synthesizing novel azulene-based dyes, pharmaceuticals, and advanced materials due to its ability to introduce the azulene moiety via amide or ester formation. It is primarily needed by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and specialty chemical industries for creating compounds with specific optical or electronic properties.

Application

• Pharmaceutical Intermediate: Serves as a crucial precursor in the synthesis of novel drug candidates, particularly those targeting anti-inflammatory or anticancer pathways where the azulene scaffold is of interest.
• Organic Synthesis Building Block: Used in amidation and esterification reactions to incorporate the azulene structure into more complex molecules for research and development.
• Functional Dye & Pigment Production: Acts as a key raw material for creating azulene-based dyes with unique color properties and potential NIR-absorbing characteristics for high-tech applications.
• Material Science Research: Employed in the development of organic semiconductors, non-linear optical (NLO) materials, and other advanced organic electronic components.
• Agrochemical Synthesis: Utilized as an intermediate in the research and development of new active ingredients with novel modes of action.
• Academic & Industrial R&D: A valuable reagent for exploring new chemical reactions and properties of azulene derivatives in university and corporate laboratories.

Quality Control

Our 1-Azulenecarbonyl Chloride, 3-Methyl- (9Ci) is produced and handled under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including purity assay and identity confirmation, to ensure it meets the high standards required for research and synthesis. A Certificate of Analysis (COA) detailing specific results is provided with every shipment to guarantee traceability and consistency for your critical applications.

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 under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent decomposition. Keep away from strong bases and moisture.
