Carbohydrazide is white crystalline powder, highly soluble in water, insoluble in alcohol, ether and benzene. It features strong reducibility and has wide industrial applications. In water‑treatment field, it is used as oxygen scavenger for boiler water. In textile industry, it can act as cross‑linking agent for elastic fiber, formaldehyde scavenger and antioxidant for pigments such as carotene. Besides, proper addition of carbohydrazide into soaps containing phenolic biocides can prevent discoloration and rancidity. It can replace hydrazine hydrate and hydroquinone. As boiler‑water oxygen scavenger, it has low toxicity, high melting point and far superior deoxygenation efficiency compared with conventional materials, making it an ideal environmentally‑friendly product.
