Dehydrated Oxalic Acid CAS 144-62-7 is a common component of herbs, which can easily enter the human body through the respiratory tract, digestive tract and skin mucosa. Because of its strong acid properties, an adult taking 2-5 grams by mistake could be fatal. Scientific studies have confirmed that feeding pregnant ewes 6 grams to 12 grams of oxalate a day can cross the placental barrier and cause oxalate crystal deposition in the kidneys of lambs.
Dehydrated Oxalic Acid CAS 144-62-7 is mainly used in the production of antibiotics, borneol and other drugs, as well as the extraction of rare metal solvents, dye reducing agents, tanning agents, etc. In addition, oxalic acid can also be used to synthesize various oxalate, oxalate and oxamide products, and diethyl oxalate, sodium oxalate, calcium oxalate and other products yield the largest.
