For professionals in the chemical manufacturing and research sectors, a deep understanding of key intermediates is essential for driving innovation and ensuring product quality. 3-Methylbenzyl Chloride, identified by CAS number 620-19-9, is a prime example of such a compound, valued for its specific properties and wide-ranging applications in organic synthesis. This article delves into its purity, physical characteristics, and crucial insights for those looking to purchase it.

The purity of chemical intermediates directly impacts the success of downstream reactions and the quality of the final product. 3-Methylbenzyl Chloride is consistently offered with a high minimum purity of 99% by Gas Chromatography (GC). This level of purity is critical for applications in sensitive fields like pharmaceuticals and specialized fragrances, where even minor impurities can lead to unwanted side reactions, reduced yields, or compromised product efficacy. Knowing this specification helps in evaluating potential suppliers and ensuring they meet stringent quality requirements.

Physically, 3-Methylbenzyl Chloride presents as a clear, colorless to light yellow liquid at room temperature. Its density is approximately 1.064 g/mL at 25°C, and it possesses a boiling point in the range of 195-196°C. These physical attributes are important for handling, storage, and integration into various chemical processes. Its solubility characteristics, being sparingly soluble in water but readily soluble in common organic solvents like ethanol and ether, further define its usability in diverse synthetic routes.

When considering the purchase of 3-Methylbenzyl Chloride, several factors are paramount for procurement professionals. Firstly, it's essential to identify a reliable manufacturer or supplier who can consistently deliver the required purity and specifications. Many suppliers are based in China, offering competitive pricing, but it is vital to vet these sources thoroughly.

Key considerations when purchasing include:

  • Quality Assurance: Always request a Certificate of Analysis (CoA) for each batch to confirm purity and other specifications.
  • Supplier Reputation: Research suppliers for their track record, customer reviews, and commitment to quality control.
  • Pricing and Volume: Compare prices from multiple vendors, especially for bulk orders, to secure cost-effectiveness.
  • Lead Times and Logistics: Understand shipping capabilities, delivery timelines, and any associated import regulations or fees.
  • Technical Support: A good supplier will offer technical assistance and readily provide Material Safety Data Sheets (MSDS) for safe handling.

The applications of 3-Methylbenzyl Chloride are extensive. It serves as a vital intermediate in the synthesis of pharmaceuticals and agrochemicals. Furthermore, its derivatives are employed in the fragrance industry, contributing to the creation of perfumes and personal care products. Its role as an alkylating agent in organic synthesis, including the formation of quaternary ammonium compounds, highlights its versatility across different chemical domains.

By focusing on these details of purity, properties, and purchasing strategies, professionals can make informed decisions when sourcing 3-Methylbenzyl Chloride, ensuring the quality and efficiency of their chemical synthesis endeavors. Working with reputable global manufacturers and suppliers is key to success in acquiring this critical intermediate.
