In the complex world of chemical procurement, identifying reliable sources for critical intermediates is paramount for success. Chloromethyl 4-Chlorophenyl Sulfide, identified by CAS number 7205-90-5, stands out as a vital component in the synthesis of numerous agrochemicals, most notably Carbophenothion. For procurement managers and R&D scientists alike, understanding the sourcing landscape and key product attributes is essential for ensuring efficient and cost-effective operations.

Understanding Chloromethyl 4-Chlorophenyl Sulfide

This compound, typically appearing as a colorless to light yellow liquid, is defined by its chemical structure and purity. With an assay requirement of ≥98.0%, it ensures that downstream reactions proceed with high efficiency and minimal by-product formation. Its physical properties, such as a boiling point of 261.9 °C and a density of 1.3 g/cm³, are critical data points for process engineers designing synthesis routes. The stability and reactive nature of the chloromethyl group, coupled with the phenyl sulfide moiety, make it an ideal electrophilic building block for organic synthesis.

The Importance of High Purity for Agrochemicals

The agrochemical industry relies heavily on the precise formulation of active ingredients and intermediates. Impurities in key precursors can lead to reduced efficacy, unwanted side reactions, and difficulties in meeting regulatory standards. Chloromethyl 4-Chlorophenyl Sulfide’s role as an intermediate means that its purity directly impacts the quality and performance of the final agrochemical product. Therefore, sourcing from a manufacturer that guarantees ≥98.0% purity is not just a preference, but a necessity.

Navigating the Supply Chain: Sourcing from China

China has emerged as a global hub for chemical manufacturing, offering a vast array of intermediates at competitive prices. For procurement managers looking to purchase Chloromethyl 4-Chlorophenyl Sulfide, identifying reputable suppliers is key. Manufacturers committed to quality control, consistent production, and transparent documentation (such as Certificates of Analysis, or COA) are invaluable partners. Engaging with suppliers who can provide stable supply chains and timely delivery is crucial for maintaining operational continuity.

Key Considerations for Procurement:

  • Supplier Reliability: Prioritize manufacturers with a proven track record and established quality management systems.
  • Product Specifications: Always verify the purity (≥98.0%), appearance, and CAS number (7205-90-5) to match your specific needs.
  • Pricing and Volume: Obtain quotes for bulk quantities to leverage economies of scale and negotiate favorable pricing.
  • Logistics and Delivery: Ensure the supplier can meet your delivery timelines and has experience with international shipping.
  • Technical Support: A supplier that offers technical data sheets (TDS) and responsive customer service can greatly facilitate your R&D and production efforts.

By focusing on these critical aspects, procurement professionals can effectively source high-quality Chloromethyl 4-Chlorophenyl Sulfide, ensuring the success of their agrochemical and industrial synthesis projects. Partnering with established manufacturers in China provides a strategic advantage in cost and availability for this essential chemical intermediate.
