    Product characteristics

    SINOGEL Company is a rarely enterprise to provide High-Optical purtiy L-Alanine in global scope.High-Optical Purity L-Alanine is the unique product of SINOGEL company.

    The content of D- alanine in the product is controlled below 0.02%, the structure is stable, and the impurity content is little.It could effectively reduce the racemization in the synthesis of other chiral compounds,help to improve the optical purty of the final product.
