Carbohydrazide, identified by the CAS number 497-18-7, is a chemical compound celebrated for its robust properties and diverse industrial applications. Understanding its fundamental chemistry is key to appreciating its value as both an oxygen scavenger and a chemical intermediate. NINGBO INNO PHARMCHEM CO.,LTD. provides high-quality Carbohydrazide, backed by a thorough understanding of its chemical nature and handling requirements.

At its core, Carbohydrazide is a derivative of hydrazine and urea, with the molecular formula CH6N4O and a molecular weight of approximately 90.08 g/mol. Its structure, often depicted as H2N-NH-CO-NH-NH2, showcases the presence of multiple nitrogen atoms and a carbonyl group, which contribute to its strong reducing power. This compound typically presents as a white crystalline powder or small columnar crystals at room temperature. It is highly soluble in water, with the dissolution process being endothermic, meaning it absorbs heat. Conversely, it shows limited solubility in alcohols, ethers, and benzene, making water its primary solvent in many applications.

The synthesis of Carbohydrazide can be achieved through various routes, often involving reactions with hydrazine derivatives. While specific synthesis pathways can vary, the goal is consistently to achieve high purity and yield. The quality standards, such as a purity of ≥99% and strict limits on free hydrazine (≤250 mg/L), are critical for its effective use, particularly in sensitive applications like pharmaceuticals and boiler water treatment. Companies that manufacture or procure Carbohydrazide must adhere to these stringent quality controls.

Safety is a paramount consideration when working with any chemical, and Carbohydrazide is no exception. While often described as having low toxicity compared to hydrazine hydrate, it is still classified as harmful if swallowed (H302) and can cause skin irritation (H315) and allergic skin reactions (H317). It is also classified as hazardous to the aquatic environment (H411). Proper handling procedures, including the use of personal protective equipment (PPE) such as gloves, eye protection, and respiratory protection, are essential. Storage should be in a cool, dry, well-ventilated area, away from heat and incompatible substances like strong acids and oxidizing agents. The compound can be explosive if heated, and caution must be exercised during processing and storage. When considering purchasing Carbohydrazide, ensuring that the supplier provides comprehensive safety data sheets (SDS) is a crucial step.

The chemical properties of Carbohydrazide, particularly its strong reducing capacity and relative stability, underpin its widespread adoption. Its ability to replace hydrazine and oximes in various applications offers a pathway to safer industrial practices. NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing detailed technical information and ensuring the highest quality standards for its Carbohydrazide products, empowering industries to utilize this vital chemical safely and effectively.
