Description
Pyrroloquinoline Quinone Disodium Salt (PQQ) is a novel cofactor with physiological functions similar to vitamins. It is widely distributed in nature, found in prokaryotes, plants (e.g., fermented soy, green pepper, kiwi, parsley, tea, papaya, spinach, celery), and mammals. The product is supplied as a reddish-brown powder with 98% purity. Its molecular formula is C14H4N2Na2O8, with a molecular weight of 374.17. PQQ is manufactured through a multi-stage chemical synthesis process, including cyclization reactions, quinoline ring formation, oxidation, and ester hydrolysis, followed by purification. For purchasers, confirmed product purity, stability, and adherence to stated specifications are crucial for ensuring the quality of the final product.
Applications
Used in the production of dietary supplements and functional foods where a cofactor with vitamin-like properties is required.
