For research scientists and product development teams in the chemical and pharmaceutical industries, understanding the fundamental building blocks of synthesis is critical. O-Xylene, scientifically known as 1,2-Dimethylbenzene and identified by CAS number 95-47-6, stands out as a versatile aromatic hydrocarbon with significant utility as a chemical intermediate. This article delves into the chemical properties and synthesis applications of O-Xylene, offering insights relevant to researchers and procurement professionals alike.

O-Xylene is a colorless liquid with a characteristic aromatic odor, closely resembling that of toluene. Its molecular structure, featuring two methyl groups attached to adjacent carbon atoms on a benzene ring, dictates its reactivity. This ortho configuration is key to its primary role in industrial chemistry: oxidation to phthalic anhydride. This conversion is a fundamental step in the production of a vast array of materials, including plasticizers, polyester resins, and certain types of dyes. Scientists utilizing O-Xylene in synthesis chains requiring phthalic anhydride can rely on its consistent purity from reputable suppliers to ensure predictable reaction outcomes.

Beyond phthalic anhydride production, O-Xylene finds application in the synthesis of other important compounds. It serves as a precursor for certain pesticides, contributing to crop protection solutions. In the pharmaceutical sector, O-Xylene can be a starting material or intermediate in the creation of specific active pharmaceutical ingredients (APIs) or their precursors. The demand for high purity O-Xylene is therefore driven by stringent quality requirements in these sensitive industries. Researchers often seek materials with minimal impurities to avoid complications in multi-step syntheses, making the sourcing of premium-grade O-Xylene a priority.

When seeking to buy O-Xylene for laboratory or pilot-scale synthesis, a thorough understanding of supplier capabilities is essential. Factors such as assay purity (e.g., ≥99%), availability of analytical documentation (like GC reports and Certificates of Analysis), and the supplier's track record are crucial. For scientists working with O-Xylene in China, identifying manufacturers who can provide this key intermediate reliably and cost-effectively is a significant advantage. Exploring options from established chemical suppliers who specialize in aromatic hydrocarbons can lead to more efficient research and development processes. If your research requires a dependable source of 1,2-Dimethylbenzene, consulting with manufacturers who prioritize quality and consistency is the best approach.

In summary, O-Xylene (CAS 95-47-6) is a vital intermediate in chemical synthesis, particularly for phthalic anhydride, dyes, pesticides, and pharmaceuticals. Researchers and procurement specialists looking for this compound should prioritize purity and supplier reliability.
