Dear Sir or Madam,

Do you offer 1-Butine (CAS 107-00-6) with a quantity of 15kg and 2,2-Dimethylpropane (CAS 463-82-1) with a quantity of 2x10kg or 1x20kg in sales cylinders? 

Furthermore, we would generally search for Methylmercaptane (CAS 74-93-1).

If you offer any alternative sizes, please let us now. 

Thank you very much.
