DL-Isoleucine Use and Manufacturing

Methods of Manufacturing

Synthesized by chemical method, using benzamidoacetic acid, methyl ethyl ketone, acetic anhydride and sodium acetate as raw materials, refluxing for several hours to obtain an oily residue, extracting with ether under alkaline conditions, and treating with red phosphorus, acetic acid and hydroiodic acid to obtain L-form and The DL-type mixture is obtained by removing DL-allo-isoleucine after acetylation, and refining it with hydr

Uses

For biochemical research, preparation of tissue culture medium.
