Description

1-Azulenecarbonylchloride(9Ci) is a specialized acyl chloride derivative of the azulene ring system, serving as a versatile and reactive synthetic intermediate. Its value lies in its ability to introduce the unique azulene moiety into target molecules, enabling the synthesis of novel compounds with potential for advanced material and pharmaceutical applications. This high-purity building block is essential for researchers and process chemists in the pharmaceutical, agrochemical, and advanced organic materials sectors seeking to explore azulene-based chemistry.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of novel active pharmaceutical ingredients (APIs) and drug candidates, particularly those leveraging the azulene scaffold's unique electronic and biological properties.
• Agrochemical Research: Used in the development of new herbicides, fungicides, and plant growth regulators where the azulene structure may impart specific bioactivity.
• Organic Electronic Materials: Serves as a precursor for dyes, pigments, and functional materials in organic light-emitting diodes (OLEDs) and non-linear optical (NLO) applications due to azulene's distinct photophysical characteristics.
• Polymer & Specialty Chemistry: Employed to functionalize polymers or create novel monomers, introducing the azulene unit to modify material properties like color, conductivity, or thermal stability.
• Academic & R&D Laboratories: A critical reagent for fundamental research in organic synthesis, medicinal chemistry, and material science exploring new reaction pathways and compound libraries.

Quality Control

Every batch of 1-Azulenecarbonylchloride(9Ci) is manufactured under strict quality management protocols. Our products undergo rigorous analytical testing, including HPLC, NMR, and FTIR, to ensure high purity and consistency suitable for research and process-scale applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (e.g., nitrogen or argon) to prevent decomposition. Keep away from strong bases and oxidizing agents.
