The pharmaceutical industry relies on a vast array of chemical compounds to synthesize active pharmaceutical ingredients (APIs) and advanced intermediates. Among these, 1,2-Dichlorobenzene (CAS 95-50-1) plays a significant role, serving as a crucial building block in the development of various therapeutics. For R&D scientists and procurement specialists, understanding the sourcing and application of this chemical is key to successful drug development and manufacturing.

1,2-Dichlorobenzene is a colorless transparent liquid with a molecular formula of C6H4Cl2. Its chemical structure, featuring two adjacent chlorine atoms on a benzene ring, imparts specific reactivity that is highly valuable in organic synthesis. The typical purity specification of ≥99.0% for pharmaceutical-grade 1,2-Dichlorobenzene is critical. This high purity ensures that downstream reactions proceed with minimal unwanted byproducts, a non-negotiable aspect in pharmaceutical manufacturing where product efficacy and patient safety are paramount.

As a pharmaceutical intermediate, 1,2-Dichlorobenzene is employed in the synthesis of a range of compounds. While specific applications are often proprietary, its utility as a precursor chemical is well-established. The rigorous standards of the pharmaceutical sector demand that suppliers provide not only high-purity materials but also comprehensive documentation, including certificates of analysis and adherence to Good Manufacturing Practices (GMP) where applicable.

For companies looking to buy 1,2-Dichlorobenzene for pharmaceutical applications, partnering with a reliable manufacturer and supplier is of utmost importance. A trusted supplier ensures consistent quality, which translates to reproducible results in complex multi-step syntheses. They can also offer competitive pricing, which is essential for managing production costs in the cost-sensitive pharmaceutical market. Furthermore, a supplier's ability to provide technical support and ensure a stable supply chain can significantly contribute to the efficiency of a pharmaceutical company's operations.

The selection of 1,2-Dichlorobenzene involves evaluating its physical properties, such as density and low water content, alongside its chemical purity. These parameters influence reaction kinetics and product isolation. When sourcing this chemical, it is advisable to consult with the manufacturer regarding storage recommendations and shelf life, typically around 12 months under appropriate conditions, to maintain its integrity.

In conclusion, 1,2-Dichlorobenzene is an essential intermediate for the pharmaceutical industry. Its high purity and specific chemical properties make it invaluable for the synthesis of APIs. For those seeking to purchase this compound, identifying a reputable manufacturer that prioritizes quality, reliability, and competitive pricing is crucial. Engaging with a knowledgeable supplier will not only secure your supply but also support your efforts in bringing vital pharmaceutical products to market.
