In the intricate world of chemical procurement and research, precision and clarity are paramount. Misidentification of a chemical compound can lead to costly errors, project delays, safety hazards, and invalid research results. This is where the Chemical Abstracts Service (CAS) Registry Number, commonly known as a CAS number, plays an indispensable role. For compounds like 3-Ethylheptan-1-ol, identified by its unique CAS number 3525-25-5, understanding its significance is vital for anyone involved in the chemical industry.

What is a CAS Number?
A CAS number is a unique numerical identifier assigned to a chemical substance by the Chemical Abstracts Service, a division of the American Chemical Society. Each CAS number consists of three parts separated by hyphens: a registrant number, a group number, and a check digit. For example, the CAS number for 3-Ethylheptan-1-ol is 3525-25-5. This system ensures that each distinct chemical entity has a universally recognized identifier, regardless of its common names, trade names, or systematic IUPAC names. This universality is critical for global commerce and scientific communication.

Why CAS Numbers are Crucial for Sourcing
When you need to buy a specific chemical, such as 3-Ethylheptan-1-ol (CAS 3525-25-5), using its CAS number is the most reliable method to ensure you are procuring the exact substance required. Here's why:

- Eliminates Ambiguity: Many chemicals have multiple common names or synonyms. For instance, 3-Ethylheptan-1-ol might be referred to by other names, but the CAS number 3525-25-5 will always point to the same unique molecule. This prevents confusion and ensures that you are ordering precisely what you need.

- Facilitates Accurate Searching: Online databases, supplier catalogs, and scientific literature often use CAS numbers as the primary search parameter. By including the CAS number in your search queries when looking for a manufacturer or supplier of 3-Ethylheptan-1-ol, you can quickly narrow down results and find the most relevant listings.

- Ensures Regulatory Compliance and Safety: CAS numbers are essential for regulatory purposes, including safety data sheets (SDS), hazard communication, and transportation regulations. Accurately identifying a chemical by its CAS number ensures that all necessary safety precautions and regulatory requirements are met.

- Supports Traceability and Quality Control: When dealing with a specific CAS number like 3525-25-5, you can more easily track the origin, batch information, and quality control documentation from your manufacturer. This is vital for maintaining the integrity of your research or production processes.

Using CAS Numbers in Procurement for 3-Ethylheptan-1-ol
When you are in the market to purchase 3-Ethylheptan-1-ol, always include the CAS number 3525-25-5 in your inquiries to suppliers. This not only helps them identify the correct product swiftly but also signals to them that you are a knowledgeable buyer. It ensures that the price quotes you receive are for the precise chemical you require, and that the specifications provided align with your needs.

In conclusion, CAS numbers are the bedrock of accurate chemical identification and sourcing. By consistently using the CAS number 3525-25-5 when procuring 3-Ethylheptan-1-ol, you can significantly enhance the efficiency, safety, and reliability of your chemical supply chain.
