1. Introduction of β-Alanine

For being one kind of powder, β-Alanine has its IUPAC name of 3-aminopropanoic acid. It is an amino acid formed in vivo by the degradation of dihydrouracil and carnosine. It is a component of the naturally occurring peptides carnosine and anserine and also of pantothenic acid (vitamin B5) which itself is a component of coenzyme A. Besides, it should be stored in sealed container, and put in a cool and dry place, away from oxidant. As to the application of β-Alanine, it can be used as electroplating corrosion inhibitors and biochemical reagents.
