For professionals engaged in organic chemistry and material science research, the reliable sourcing of specific chemical intermediates is paramount. One such crucial compound is 9-Ethyl-3-carbazolecarboxaldehyde, identified by CAS number 7570-45-8. This article aims to guide R&D professionals on the essential considerations when seeking to purchase or procure this valuable molecule.

Understanding the Compound: Properties and Purity

9-Ethyl-3-carbazolecarboxaldehyde is typically presented as a white crystalline powder. Key physical properties, such as its melting point (85-87 °C) and stability under normal storage conditions, are critical for handling and successful integration into synthesis processes. For R&D applications, purity is a non-negotiable factor. Manufacturers often specify a minimum purity of 95% or higher (e.g., ≥98.0% by GC), ensuring that the intermediate does not introduce unwanted side reactions or contaminants into your valuable research projects.

Key Considerations for Procurement

When looking to buy 9-Ethyl-3-carbazolecarboxaldehyde, several factors should be prioritized:

  • Supplier Reputation: Partnering with established chemical suppliers or direct manufacturers is crucial. Look for suppliers with a proven track record of delivering high-quality products and consistent supply. Consider manufacturers based in China, known for their robust chemical production capabilities.
  • Purity Specifications: Always verify the reported purity of the compound. For demanding R&D, requesting a Certificate of Analysis (COA) detailing lot-specific purity and analytical data is a standard practice.
  • Packaging and Quantity: The availability of various packaging sizes, from grams for laboratory use to kilograms for pilot-scale production, is important. Ensure the supplier can meet your required quantities.
  • Technical Support: A good supplier will offer technical support to answer queries regarding product specifications, handling, and potential applications.

Applications and Market Demand

9-Ethyl-3-carbazolecarboxaldehyde serves as a versatile building block in various organic synthesis pathways. Its applications span the creation of advanced materials, including polymers and organic electronic components, and it is also recognized as a key intermediate in the pharmaceutical sector for the synthesis of active pharmaceutical ingredients (APIs). Understanding these applications can help you better articulate your needs when interacting with a manufacturer.

Pricing and Availability

The price of 9-Ethyl-3-carbazolecarboxaldehyde can vary based on purity, quantity, and the supplier. Engaging directly with a manufacturer or a reliable distributor can often lead to more competitive pricing and better lead times. For bulk purchases or long-term supply agreements, negotiating directly with a supplier in China can be particularly advantageous for cost-efficiency.

In conclusion, sourcing 9-Ethyl-3-carbazolecarboxaldehyde requires careful consideration of product quality, supplier reliability, and application requirements. By focusing on these aspects, R&D professionals can secure the essential materials needed to drive their research forward.
