L-stachydrine

L-Stachydrine (CAS 471-87-4), also known as stachydrine, L-proline betaine, and cadabine, is a naturally occurring betaine alkaloid found in various plant species including alfalfa and citrus fruits. It carries no assigned E-code and is classified within the amino acids and peptides category.

In pharmaceutical and nutraceutical formulations, L-stachydrine functions as an antioxidant by scavenging reactive oxygen species and stabilising sensitive active ingredients against oxidative degradation. It is also investigated in biotechnology applications as an osmoprotectant, where it helps maintain cellular integrity under osmotic stress conditions.

L-Stachydrine is supplied as a solid and is available in research and commercial grades suited to pharmaceutical and food and nutrition applications. It falls under HS code 29214980 and is subject to REACH registration requirements for EU supply. Buyers should confirm grade specifications and documentation requirements prior to ordering.
