For professionals in the chemical industry, staying informed about key raw materials and intermediates is crucial for efficient procurement and successful synthesis projects. 3-Methylbenzyl Chloride, identified by CAS number 620-19-9, is one such compound that plays a significant role in various chemical transformations. This article serves as a guide for chemical buyers, highlighting the essential aspects of this intermediate, its applications, and how to source it effectively, particularly from China.

3-Methylbenzyl Chloride is an organic compound classified as a halogenated hydrocarbon. Its chemical structure, often referred to by synonyms such as alpha-Chloro-m-xylene, features a meta-substituted methyl group on a benzene ring, with a chloromethyl substituent. This molecular architecture, with a formula of C8H9Cl and a molecular weight of 140.61, makes it a reactive intermediate. It is typically supplied as a clear, colorless to slightly yellow liquid, with manufacturers often guaranteeing a purity of 98% or higher. This high purity is vital for its applications, especially in sensitive synthesis pathways found in the pharmaceutical industry.

The primary function of 3-Methylbenzyl Chloride in the chemical industry is its utility as a synthetic intermediate. It acts as a crucial building block for creating more complex organic molecules. Its reactivity allows chemists to introduce the 3-methylbenzyl group into various compounds through reactions like alkylation and nucleophilic substitution. This makes it indispensable for synthesizing a wide range of products, including pharmaceuticals, specialty chemicals, and research compounds. For instance, it can be a precursor to molecules like p-methylbenzyl alcohol or used in custom synthesis to create novel materials.

When considering the purchase of 3-Methylbenzyl Chloride, buyers must prioritize identifying suppliers who can consistently deliver on quality and quantity. China has emerged as a significant hub for chemical manufacturing, offering a vast array of intermediates at competitive prices. However, thorough supplier vetting is essential. Prospective buyers should look for manufacturers that provide detailed product specifications, safety data sheets (SDS), and Certificates of Analysis (CoA). Establishing a relationship with a reputable supplier ensures not only product quality but also supply chain reliability, whether for small laboratory orders or large industrial purchases.

For procurement managers and R&D scientists, understanding the precise needs for 3-Methylbenzyl Chloride is key. Factors such as the required purity level, packaging (e.g., 200 kg/drum), and delivery timelines will influence the choice of supplier. It is always advisable to obtain quotations from multiple reputable manufacturers to compare pricing, lead times, and service offerings. This diligence ensures that you secure the best possible value for your investment in this critical chemical intermediate.

In summary, 3-Methylbenzyl Chloride (CAS 620-19-9) is a valuable intermediate for diverse synthetic applications. By understanding its chemical properties, applications, and focusing on sourcing from quality-conscious manufacturers, chemical buyers can effectively integrate this compound into their production processes, driving innovation and efficiency.
