Exploring Chemical Properties and Applications of CAS Number 26172-55-4

The Importance and Applications of CAS Number 26172-55-4

Chemical substances play a vital role in various industries, and the uniqueness of each compound makes it essential to identify them accurately. One of the systems used for classifying chemical substances is the Chemical Abstracts Service (CAS) registry. Every chemical is assigned a unique CAS number, which serves as a standardized identifier. An interesting example is CAS number 26172-55-4, associated with a compound that has significant implications in numerous fields, particularly in medicinal chemistry and industrial applications.

CAS number 26172-55-4 corresponds to the chemical compound known as 1,2-Benzenedicarboxylic acid, di-C9-11-branched alkyl esters, which is commonly referred to as diisononyl phthalate (DINP). This compound falls under the category of phthalates, a group of chemicals widely used as plasticizers – substances that are added to plastics to increase their flexibility, transparency, durability, and longevity.

Phthalates, including DINP, are primarily utilized in the production of polyvinyl chloride (PVC), which is a ubiquitous material found in many products from flooring and piping to medical devices and toys. The versatility of DINP makes it a preferred choice in the manufacturing of flexible PVC products, allowing them to maintain their functionality while resisting cracking and degradation over time.

Applications of DINP

The widespread application of DINP is remarkable. It can be found in various sectors including construction, automotive, and consumer goods. In construction, DINP is often used in flooring materials, wall coverings, and electrical cables, providing both flexibility and resilience to these components.

In automotive manufacturing, DINP is utilized to create flexible dashboard materials and interior components. The stability and durability that DINP provides help maintain the aesthetic appeal and functionality of vehicles over their lifespan. Similarly, in consumer goods, the compound is found in a variety of products, from children's toys to household items, ensuring safety and usability.

Beyond its application in plastics, DINP also has a role in the formulation of adhesives, coatings, and sealants. The addition of DINP enhances the performance characteristics of these products, allowing them to withstand different environmental conditions while remaining effective.

Safety and Regulatory Considerations

Despite its benefits, the use of phthalates, including DINP, has raised concerns regarding potential health effects. Various studies have suggested that exposure to certain phthalates may disrupt endocrine function and affect reproductive health. Consequently, regulatory agencies around the world, including the European Chemicals Agency (ECHA) and the U.S. Environmental Protection Agency (EPA), have taken measures to evaluate the safety of phthalate use.

DINP, however, has been found by many regulatory bodies to be safer for consumer use when compared to other phthalates. It has been classified as having a lower risk profile, leading to its continued usage in many applications under specific regulatory conditions. Manufacturers must comply with regulations ensuring product safety and transparency, including proper labeling and consumer education regarding the ingredients used in their products.

The Future of DINP and Phthalates

Looking ahead, the landscape for chemicals such as DINP is likely to continue evolving. As sustainability becomes a priority, manufacturers are actively seeking alternatives to traditional phthalates, including bio-based plasticizers that offer reduced environmental impacts. Research and innovation will play crucial roles in determining the future applications of DINP and whether it can coexist with emerging materials in the industry.

In conclusion, CAS number 26172-55-4 encapsulates the significance of diisononyl phthalate in modern manufacturing and consumer products. Its role as a plasticizer is indispensable, providing essential characteristics that enhance the usability of a wide range of materials. With appropriate regulatory oversight and ongoing research into safer alternatives, DINP is poised to remain a valuable compound in various applications while ensuring consumer safety and environmental responsibility.
