Description

Carbohydrazide is a versatile and highly effective oxygen scavenger and reducing agent with the CAS number 497-18-7. This white, crystalline solid is critical for preventing corrosion and oxidative degradation in complex industrial systems. It is an essential raw material for manufacturers in the water treatment, polymer, and pharmaceutical industries seeking reliable, high-purity chemical intermediates.

Application

• Oxygen Scavenger in Boiler Water Treatment: Primary application for preventing corrosion in high-pressure steam-generating systems by rapidly removing dissolved oxygen.
• Polymer Industry: Used as a chain extender, cross-linking agent, and blowing agent precursor in the production of polyurethanes, polycarbonates, and other specialty polymers.
• Pharmaceutical Intermediate: Serves as a key building block in the synthesis of various active pharmaceutical ingredients (APIs) and heterocyclic compounds.
• Photography and Imaging: Acts as a reducing agent in photographic developers and in the manufacture of thermal paper.
• Metal Surface Treatment: Employed in metal plating and finishing processes to improve adhesion and corrosion resistance.
• Agrochemical Synthesis: Intermediate in the production of certain herbicides, plant growth regulators, and pesticides.
• Textile Industry: Used in dyeing processes and as a reducing agent for vat dyes.
• Laboratory Reagent: Utilized in analytical chemistry as a derivatization agent and in organic synthesis research.
