For professionals in the chemical and pharmaceutical industries, precision and reliability are paramount. When procuring specialty chemicals like 6-Undecanol (CAS 23708-56-7), a thorough understanding of its specifications is crucial. This guide aims to break down the key details that B2B buyers, from procurement managers to R&D scientists, need to consider when sourcing this versatile fatty alcohol.

What is 6-Undecanol?

6-Undecanol, also known by synonyms such as undecan-6-ol or diamyl carbinol, is a secondary alcohol with the molecular formula C11H24O. Its molecular weight is approximately 172.31 g/mol. As a fine chemical intermediate, it finds application in various organic synthesis routes and specialized industrial processes. Identifying the correct CAS number, 23708-56-7, is the first step in ensuring you are sourcing the exact compound required.

Key Specifications for Buyers

When evaluating offers from manufacturers and suppliers, pay close attention to the following specifications:

• Purity: This is arguably the most critical specification. 6-Undecanol is often available with purities of 97% or higher, typically determined by Gas Chromatography (GC). Higher purity is essential for sensitive applications in pharmaceuticals or advanced materials. Always request a COA that details the purity and any significant impurities.
• Physical Appearance: The product is typically described as a white to light yellow powder or crystalline solid. Variations in color or form can sometimes indicate processing differences or impurities, so it's important to align with your requirements.
• Melting Point: The melting point of 6-Undecanol is reported to be in the range of 25-26°C. This relatively low melting point means it can exist as a liquid at slightly elevated ambient temperatures.
• Boiling Point: At standard atmospheric pressure (760 mmHg), 6-Undecanol boils at approximately 229.7°C. This data is vital for processes involving distillation or high-temperature reactions.
• Density: Reported densities are around 0.828 g/cm³ to 0.83 g/cm³. This information is useful for volumetric calculations and material handling.
• Flash Point: The flash point is around 94°C, indicating it is a combustible liquid. Safety handling procedures should be based on this parameter.
• Solubility: Information on solubility (e.g., slightly soluble in methanol, sparingly soluble in chloroform) helps in designing reaction or purification protocols.

Supplier Information and Commercial Aspects

Beyond technical specifications, commercial aspects are equally important for B2B buyers. When you buy 6-undecanol, consider:

• Manufacturer vs. Distributor: Decide whether to source directly from a manufacturer or through a distributor. Direct sourcing often offers better pricing but may require higher MOQs, while distributors can offer flexibility for smaller quantities.
• Packaging and Delivery: Confirm packaging options (e.g., grams, kilograms) and delivery methods (Ocean, Land, Air, courier services like DHL/TNT). Discuss Incoterms and lead times.
• Payment Terms: Standard payment methods like T/T, L/C, and PayPal are generally accepted. Clarify terms to ensure smooth transactions.

By carefully reviewing these specifications and commercial details, procurement professionals can confidently select the right 6-Undecanol product and supplier, ensuring the success of their critical chemical processes.
