Understanding the precise chemical identity of a compound is the first step in harnessing its potential applications. For 2,3-dimethylpyridine, a versatile fine chemical, its identity is firmly established through key identifiers such as its CAS (Chemical Abstracts Service) number, molecular formula, and IUPAC name. The CAS number 583-61-9 serves as a unique, unambiguous identifier that is recognized globally by chemists, regulatory bodies, and the scientific community. This ensures that when one refers to 2,3-dimethylpyridine, there is no confusion with other similar compounds.

The molecular formula for 2,3-dimethylpyridine is C7H9N. This formula indicates that each molecule is composed of seven carbon atoms, nine hydrogen atoms, and one nitrogen atom. This fundamental information is crucial for stoichiometric calculations in chemical reactions, determining molecular weight, and understanding the basic building blocks of the compound. As a derivative of pyridine, the nitrogen atom within the aromatic ring plays a significant role in its chemical behavior, contributing to its basicity and its ability to act as a ligand.

Beyond the CAS number and molecular formula, other identifiers like synonyms and EINECS numbers (European Inventory of Existing Commercial Chemical Substances) further aid in precise identification and regulatory compliance. Synonyms for 2,3-dimethylpyridine include terms like 2,3-lutidine, reflecting its nature as a dimethyl-substituted pyridine. The EINECS number, 209-514-1, is important for trade and regulation within the European Union. These detailed pieces of information are vital for anyone looking to buy 2,3-dimethylpyridine or use it in industrial or research settings.

The reliable provision of such chemical identity data by suppliers is a testament to their professionalism and commitment to quality. Whether for use as a solvent, a pharmaceutical intermediate, or in other fine chemical applications, accurate identification is the bedrock of safe and effective utilization. Researchers and industry professionals can trust that when they source 2,3-dimethylpyridine, the specified CAS number and molecular formula will lead them to the correct chemical entity.
