General description

Methanolic HCl (hydrochloric acid in methanol) is particularly useful for preparing methyl esters of volatile (short chain) fatty acids. Fatty acids are esterified by heating them with an anhydrous alcohol (e.g., methanol) in the presence of an acidic catalyst (e.g., HCl) in a sealed vessel at a high temperature for a short time. In the reaction, a fatty acid molecule and an alcohol molecule are joined, with the release of a water molecule. The derivatives can be quickly and easily recovered, quantitatively, from the reaction medium.

Features and Benefits

  • Derivatization of fatty acids, particularly volatile (short chain) fatty acids.

  • Clean reaction (no side reaction) with volatile by-products.

  • Provides clean, fast, quantitative derivatization.

  3. When using 3N Methanolic HCl, Product 33051, how long should I let the reaction go?

    The typical procedure for forming methyl esters will have the mixture heated at 50°C for 5-10 minutes.  However, we recommend that you sample at other time intervals to ensure that your reaction has gone to completion.

  4. With which compounds should I use the Methanolic HCl, Product 33051?

    The  3N Methanolic HCl reagent works best for derivatizing short chain fatty acids (C4-C8).  However, it can be used for C9 and longer, but you may see a decrease in recoveries for some of the longer chains.

  5. Is Product 33051, Methanolic HCl, only used to make derivatives for GC analysis?

    The methyl esters formed by use of this reagent can be used for both TLC and HPLC applications.
