Carbohydrazide, identified by its Chemical Abstracts Service (CAS) number 497-18-7, stands as a highly versatile and effective chemical compound. This white crystalline powder is widely recognized and utilized across numerous industrial sectors, primarily for its potent properties as an oxygen scavenger, particularly in boiler systems. With a molecular formula of CH6N4O and a molecular weight of 90.08, Carbohydrazide is also known by synonyms such as 1,3-Diaminourea and Carbonic dihydrazide. Its unique chemical structure, derived from urea, grants it significant reactivity, making it invaluable in various chemical processes and applications.

The primary and arguably most critical application of Carbohydrazide is its use in water treatment, specifically as an oxygen scavenger in boilers and heating systems. Dissolved oxygen in boiler feedwater is a major contributor to corrosion, which can lead to equipment damage, reduced efficiency, and costly downtime. Carbohydrazide effectively removes dissolved oxygen through a chemical reaction, forming non-corrosive products like water, nitrogen, and ammonia. This reaction is generally faster and more complete at elevated temperatures, making it ideal for high-pressure boiler systems. Unlike older oxygen scavengers like hydrazine, Carbohydrazide offers a significant advantage in terms of safety and environmental impact. Hydrazine is known for its toxicity and potential carcinogenicity, prompting a shift towards safer alternatives. Carbohydrazide is considered less toxic, easier to handle, and its decomposition products are less hazardous, making it a preferred choice for modern water treatment practices.

Beyond its role in boiler water treatment, Carbohydrazide demonstrates remarkable versatility. Its strong reducing properties allow it to be used as an energy material or as a reducing agent in various chemical syntheses. In the chemical fiber industry, it serves as an effective crosslinking agent, particularly for elastic fibers, improving their physical properties and durability. The compound's reactivity also makes it a valuable intermediate in the synthesis of a wide range of other chemicals. This includes its use in the production of pharmaceuticals, agrochemicals such as herbicides and plant growth regulators, and various types of dyes. Its incorporation into these complex molecules leverages its specific functional groups, enabling the creation of diverse end products with tailored properties.

The chemical stability of Carbohydrazide in its solid form, coupled with its high purity, typically 99% or higher, ensures reliable performance in its intended applications. It is supplied as a fine white crystalline powder, facilitating ease of handling and dissolution in water, which is crucial for its application in liquid systems like boiler feedwater. Proper packaging, often in durable bags or fiber drums, protects the product during storage and transportation, maintaining its quality until it is ready for use. Understanding the physical properties, such as its melting point around 152-153 °C, is also important for safe handling and storage.

The demand for high-quality Carbohydrazide is steady, driven by the continuous need for efficient and safe water treatment in power generation, petrochemicals, and heavy industry, as well as growth in the agricultural and specialty chemical sectors. Its multifunctional nature ensures its relevance in ongoing chemical research and development, promising potential new applications. As industries increasingly prioritize sustainability and safety, the adoption of chemicals like Carbohydrazide that offer better environmental profiles compared to traditional options is expected to continue growing. This trend underscores the importance of reliable sourcing and consistent quality in the supply chain for this critical chemical intermediate.

When considering the procurement of this essential chemical, various factors come into play. If you are looking to find a reliable Carbohydrazide manufacturer, it is important to seek out entities with established production capabilities and rigorous quality control processes. Sourcing from a reputable supplier ensures not only product purity and consistency but also reliable logistics and technical support. Understanding the price of Carbohydrazide involves considering factors such as purity, quantity ordered, packaging requirements, and market conditions. Comparing quotes and negotiating terms are standard practices when looking to buy Carbohydrazide. The process to purchase Carbohydrazide typically involves specifying your required quantity, quality standards (like 99% purity), and desired packaging, followed by order confirmation and delivery arrangements. Building a long-term relationship with a trusted provider is often beneficial for ensuring a stable supply at competitive terms.

In summary, Carbohydrazide (CAS 497-18-7) is a crucial chemical compound with significant applications, particularly as a safe and effective oxygen scavenger in boiler water treatment. Its versatility as a reducing agent, crosslinking agent, and chemical intermediate further highlights its importance across diverse industries, from textiles and agriculture to pharmaceuticals and dyes. Its favorable safety profile relative to alternatives solidifies its position as a key chemical for modern industrial processes.
