    n-Undecane CAS 1120-21-4

    n-Undecane is supplied as a straight-chain (C11) alkane hydrocarbon, typically used in applications where defined hydrocarbon structure and controlled volatility are required. It is positioned as a specialty solvent and reference compound rather than a bulk fuel component.

    In industrial and laboratory contexts, n-Undecane is used as a reference standard in analytical work, a calibration component in fuel or hydrocarbon analysis, and as a solvent or intermediate in chemical processing systems. It is generally supplied as a clear liquid suitable for direct use or blending. Standard packaging, bulk supply, and technical documentation such as COA, TDS, and SDS are available to support procurement and application needs.

    • Intermediate in controlled hydrocarbon formulation systems

    Packaging

    n-Undecane is supplied as a liquid and is typically packed in sealed drums, metal cans, or other suitable containers for hydrocarbon products. Packaging is selected to ensure safe transport, minimize evaporation, and maintain product purity. Bulk supply options can be arranged depending on order size and logistics requirements.

    Storage

    Store in a cool, well-ventilated area away from sources of ignition and direct sunlight. Keep containers tightly closed when not in use to prevent evaporation and contamination. Handle and store in accordance with standard practices for flammable hydrocarbon liquids.

    FAQ

    Can it be supplied in bulk quantities?
    Bulk supply can be arranged depending on order volume and transportation conditions.

    What type of product is n-Undecane?
    It is a linear alkane hydrocarbon used as a solvent, reference material, and intermediate.

    Is n-Undecane used as a fuel?
    It may be studied in fuel research, but it is typically supplied as a defined hydrocarbon for laboratory or industrial use rather than as a commercial fuel product.

    In what form is it supplied?
    It is supplied as a clear liquid suitable for direct use or blending.

    What packaging options are available?
    Common packaging includes drums, cans, or other sealed containers for liquid hydrocarbons.

    Are safety documents available?
    Yes, SDS along with COA and TDS can be provided for handling and application reference.

    • Packing information for sample, trial, and bulk orders
    • Technical communication based on application and specification requirements
    Quotation

    Information to Confirm Before Quotation

    Clear sourcing information helps reduce specification mismatch and allows a more accurate quotation before sample or bulk order discussion.

    • Product name and CAS number
    • Application or intended end use
    • Required purity, grade, or specification
    • Sample quantity, trial order, or bulk demand
    • Preferred packing form or net weight
    • Destination country or port
    • Required documents or compliance expectations
    Storage & Handling

    Packaging, Storage, and Handling Notes

    Packaging form, storage conditions, shelf life, and shipment arrangements should be confirmed according to the product characteristics, package size, and destination requirements.

    Before order confirmation, buyers are advised to review the corresponding product documents and confirm whether any special storage, labeling, or handling requirements apply.

    Supply Support

    Sample, Bulk Order and Repeat Supply Support

    Support can be arranged for sample discussion, bulk supply planning, packaging confirmation, and routine sourcing communication based on the actual product and order requirements.

    For repeat-use formulations or long-term procurement plans, buyers may discuss specification consistency, packaging preferences, delivery expectations, and document coordination in advance.
