In the vast and complex world of chemistry, precise identification of substances is fundamental for research, regulatory compliance, and commerce. The Chemical Abstracts Service (CAS) Registry Number, commonly known as a CAS number, is an internationally recognized unique identifier for chemical substances. Each CAS number is a string of digits separated by hyphens, with no inherent chemical meaning, but providing an unambiguous way to refer to a specific compound, distinct from its various names or synonyms.

For researchers and procurement specialists, using CAS numbers is crucial for avoiding confusion and ensuring accuracy. For example, 6-bromo-4,4-dihexyl-4H-cyclopenta[2,1-b:3,4-b′]dithiophene-2-carbaldehyde is identified by the CAS number 1221821-39-1. This specific number ensures that when you search for this compound, or when you communicate with a supplier about purchasing it, there is no ambiguity about the substance being discussed. This precision is vital for sourcing materials like this heterocyclic compound, ensuring that the correct C22H29BrOS2 molecule is acquired.

As a reputable chemical manufacturer and supplier in China, we place great emphasis on accurate product identification through CAS numbers. When you need to buy 6-bromo-4,4-dihexyl-4H-cyclopenta[2,1-b:3,4-b′]dithiophene-2-carbaldehyde, including its CAS 1221821-39-1 in your inquiry helps us serve you more efficiently and accurately. We understand that consistent supply of chemicals with correct CAS identification is critical for your research and production workflows. The price quoted will be for the precisely identified chemical.

The CAS Registry is the most comprehensive and authoritative source of chemical information globally. Each new chemical substance reported in the literature is assigned a unique CAS RN. Therefore, when looking for specific organic intermediates or complex heterocyclic compounds, using the CAS number in your search query and purchase order is a best practice. It guarantees that you are obtaining the exact chemical entity you require for your applications, whether it's for advanced materials or other chemical synthesis pathways.

We encourage all our clients to utilize CAS numbers in their inquiries and orders. This practice simplifies the procurement process, reduces the risk of errors, and ensures that you receive the correct product, such as 6-bromo-4,4-dihexyl-4H-cyclopenta[2,1-b:3,4-b′]dithiophene-2-carbaldehyde, from reliable manufacturers like us.
