  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. How are the 100 mL, 800 mL, and 1 L unit sizes of Product 186171, Butyllithium solution, packaged?

    They are packaged in our Sure-Seal™ bottle, which have a crown cap with a PTFE/elastomer liner crimped into place.

  4. How are the 8 L and 18 L unit sizes of Product 186171, Butyllithium solution, packaged?

    They are packaged in our Kilo-Lab™ cylinder.

  5. What should I do if precipitate is present in Product 186171, Butyllithium solution?

    Haziness may form upon storage but does not affect the specification. If precipitation is present, then gently mix precipitate back into solution under an inert atmosphere.

  6. What are common uses for Product 186171, Butyllithium solution?

    Butyllithium is widely use as a polymerization initiator in the production of elastomers such as polybutadiene or styrene-butadiene-styrene (SBS).  It is also broadly employed as a strong base (superbase) in organic synthesis, both industrially and in the laboratory.

  7. Is it necessary to handle Product 186171, Butyllithium solution, under inert atmosphere?

    This product ignites on exposure to air and should be handled under inert atmosphere such as under nitrogen.

Two-dimensional (2D) semiconducting monolayer transition metal dichalcogenides (TMDCs) have stimulated lots of interest because they are direct bandgap materials that have reasonably good mobility values. However, contact between most metals and semiconducting TMDCs like 2H phase WSe2 are highly resistive
