China Supply 3,4-dihydroxybenzoic acid
3,4-dihydroxybenzoic acid,also known as protocatechuic acid,is a white to light brown needle-like crystal found naturally in vegetables,fruits,tea leaves,nuts,whole grains and some grasses.It is soluble in hot water, ethanol,ether,slightly soluble in cold water,and insoluble in benzene.
When 3,4-dihydroxybenzoic acid is placed in boiling water,it breaks down and releases carbon dioxide.Aqueous solutions of 3,4-dihydroxybenzoic acid change color to green when encountered with ferric chloride and dark red when encountered with sodium bicarbonate.When we store 3,4-dihydroxybenzoic acid,it is not suitable to be mixed with strong oxidant and alkali for storage or transportation.It is suggested to store it in a ventilated,cool,dry warehouse with professional explosion-proof function,away from fire and heat source.
3,4-dihydroxybenzoic acid,as a precursor for the synthesis of other complex molecules,has diversified biological activities.It can not only play anti inflammatory,antibacterial,antioxidant,anti-hyperglycemia and nerve protection,but also has potential chemical protection and can play a certain inhibitory effect on chemical carcinogens in vitro. In practical clinical application,
3,4-dihydroxybenzoic acid can mainly treat bacterial dysentery,burn,pneumonia in children,acute pancreatitis,acute pyelonephritis and some ulcer diseases.
In addition to its application in the medical industry,3,4-dihydroxybenzoic acid can also be used as a dye intermediate in the dye industry, and can also be used as an analytical reagent to detect iron and its content.
Shipping & Storage
Due to certain requirements on temperature and humidity, it is recommended to place protocatechuic acid in a cool, dry and dark environment. At the same time, it should be kept away from fire and heat sources, and stored separately from oxidizer and strong alkali.
