L-Alanine CAS 56-41-7

Product name: L-Alanine Molecular Structure: L-丙氨酸结构式.png Molecular Weight: 89.09 CAS No.: 56-41-7 Description L-Alanine occurs as a white crystalline powder. It is freely soluble in water, sparingly soluble in alcohol, and insoluble in ether. The pH of a 1:20 aqueous solution is between 5.5 and 7.0. Application L-alanine is an important raw material for the synthesis of VB6. Used as a food additive, it can improve the nutritional value of the food, improve the taste of the artificial sweetener, and increase the sweetness and reduce the dosage.
