The CAS (Chemical Abstracts Service) number is a unique identifier assigned to a specific chemical substance, such as HEDP•Na₄ Granule. While CAS itself is not directly involved in the chemical function or role of a compound, it serves important administrative and identification purposes in the chemical and regulatory sectors. Here’s a breakdown of the role and relevance of CAS in the context of HEDP•Na₄ Granule:
1. Identification and Cataloging
CAS Number: The CAS number for HEDP•Na₄ is 3794-83-0. This number acts as a unique identifier, allowing for precise identification of the compound across different databases, research papers, and regulatory documents.
Purity and Specifications: The CAS number ensures consistency in the identification of the substance, which helps determine its purity, molecular structure, and regulatory status.
Database and Research: Researchers and manufacturers use the CAS number to quickly find detailed information about the compound, such as its synthesis, physical and chemical properties, and applications.
2. Regulatory Compliance
Chemical Regulation: CAS numbers are used in regulatory frameworks (like REACH in Europe, TSCA in the U.S., and others) to track chemicals’ compliance with safety, environmental, and health regulations.
Safety Data: The CAS number is often included in safety data sheets (SDS), which provide information about the safe handling, transport, storage, and disposal of the chemical.
Classification and Labeling: Regulatory bodies use CAS numbers to classify substances according to their hazards (e.g., toxicity, environmental impact) and to ensure proper labeling in accordance with global standards like GHS (Globally Harmonized System of Classification and Labeling of Chemicals).
3. Commercial and Market Use
Supply Chain Management: The CAS number helps suppliers, distributors, and customers ensure that they are purchasing or using the correct substance. In the case of HEDP•Na₄ Granule, this is especially important since there are various salts and derivatives of HEDP (like HEDP•Na₂, HEDP•Na₃), which could have different uses and properties.
Trademark and Branding: Manufacturers may use the CAS number to distinguish their product from others in the market and may also use it to advertise the quality and reliability of their product.
4. Chemical Safety and Environmental Impact
Toxicological Data: The CAS number is linked to toxicological data for HEDP•Na₄ Granule, allowing users to determine the substance’s safety profile, including any associated risks in case of exposure.
Environmental Impact: CAS numbers also help in tracking the compound’s environmental impact (e.g., biodegradability, water toxicity) and its compliance with environmental protection laws.
5. Synthesis and Applications
Chemical Synthesis: In scientific literature, CAS numbers are often used to describe the synthesis pathways and reactions involving specific chemicals like HEDP•Na₄ Granule.
Applications: In applications like water treatment, HEDP•Na₄ Granule is used as a scale inhibitor and corrosion inhibitor. The CAS number allows stakeholders to verify the correct compound is being utilized for the intended industrial purposes.
Conclusion:
In summary, the CAS number for HEDP•Na₄ Granule (3794-83-0) plays a crucial administrative and identification role in ensuring that the compound is properly regulated, safely handled, and accurately identified across various industries, research fields, and commercial applications. It aids in regulatory compliance, tracking, and facilitates communication among suppliers, manufacturers, and users. However, CAS itself does not contribute to the chemical properties or function of HEDP•Na₄ Granule, which is primarily used for scale inhibition and corrosion prevention in water treatment and other applications.
