In the complex world of chemistry, precise identification of compounds is paramount. The Chemical Abstracts Service (CAS) Registry Number, or CAS number, serves as a unique numerical identifier for chemical substances. For researchers and procurement specialists, understanding and correctly using CAS numbers is fundamental when looking to buy specific chemicals, such as 3,4-DIHYDRO-1H-PYRIDO[1,2-A]PYRIMIDIN-6(2H)-ONE (CAS 1000981-74-7).

What is a CAS Number?

A CAS number is a globally recognized, unique identifier assigned to a specific chemical substance. It consists of three parts separated by hyphens: the first two digits, followed by a hyphen, then a group of digits, followed by another hyphen, and finally a single check digit. For instance, the CAS number for 3,4-DIHYDRO-1H-PYRIDO[1,2-A]PYRIMIDIN-6(2H)-ONE is 1000981-74-7.

Why are CAS Numbers Important?

CAS numbers are indispensable for several reasons:

• Unambiguous Identification: They eliminate ambiguity associated with chemical names, which can often have multiple synonyms or variations. When you search to buy a specific compound, using its CAS number ensures you are getting the exact substance required.
• Global Standardization: CAS numbers provide a universal language for chemical identification, facilitating international trade and scientific communication.
• Regulatory Compliance: Regulatory bodies worldwide rely on CAS numbers for substance tracking, hazard assessment, and compliance management.
• Database Searching: In scientific literature and chemical databases, CAS numbers are essential for precise searching and data retrieval, making it easier to find information on properties, synthesis methods, and suppliers for compounds like 3,4-DIHYDRO-1H-PYRIDO[1,2-A]PYRIMIDIN-6(2H)-ONE.

Using CAS Numbers When Purchasing

When you intend to buy 3,4-DIHYDRO-1H-PYRIDO[1,2-A]PYRIMIDIN-6(2H)-ONE or any other chemical intermediate, always verify the CAS number provided by the supplier. This confirms that you are procuring the correct material for your chemical synthesis or pharmaceutical research. Reputable manufacturers, such as ourselves, prominently display the CAS number on product specifications and documentation, ensuring clarity and accuracy for our customers.

The molecular formula (C8 H10 N2 O) and molecular weight (150.1778) provide additional context, but the CAS number offers the most definitive identification. Trusting a supplier who meticulously provides accurate CAS information for their products, like our 98% HPLC purity 3,4-DIHYDRO-1H-PYRIDO[1,2-A]PYRIMIDIN-6(2H)-ONE, is key to successful procurement and research.
