Carbohydrazide Oxygen Scavenger
Carbohydrazide (CHZ) is an organic oxygen scavenger and metal passivator used as a safer alternative to hydrazine in high-pressure boiler and steam generation systems. It decomposes at elevated temperatures to yield nitrogen and water, with no harmful residuals, while also passivating iron and copper surfaces to form protective magnetite/cuprous oxide films.
