Oxalic acid dihydrate（Cat No.:R069571）is the crystalline, hydrated form of oxalic acid, with the formula (COOH)₂·2H₂O. It appears as a colorless, odorless solid that is soluble in water and alcohol. Naturally occurring in many plants like spinach and rhubarb, it is used industrially as a cleaning agent, bleaching agent, and metal chelator. In laboratories, it serves as a reducing agent and reagent in analytical chemistry. Though useful, oxalic acid is toxic in high concentrations, capable of forming insoluble calcium oxalate crystals, which can lead to kidney damage upon ingestion.
