For procurement managers and R&D scientists in the chemical and pharmaceutical industries, sourcing high-quality intermediates is paramount. Diethyl 2,5-dibromoterephthalate (CAS: 18013-97-3) is one such critical compound, widely used in the synthesis of advanced organic materials and as a pharmaceutical intermediate. Understanding where to buy this product and what to look for ensures efficient and successful project execution. This guide aims to assist buyers in navigating the procurement process, focusing on identifying reliable manufacturers and suppliers.

Understanding Diethyl 2,5-Dibromoterephthalate

Diethyl 2,5-dibromoterephthalate is an organic compound characterized by its dibrominated benzene ring substituted with two ethyl ester groups. Its molecular formula is C12H12Br2O4, and it typically presents as a white to yellow crystalline powder. The presence of bromine atoms makes it an excellent substrate for various cross-coupling reactions, such as Suzuki-Miyaura coupling, which are fundamental in constructing complex molecular architectures. Its utility spans across sectors, particularly in material science for the development of organic electronics and in the pharmaceutical industry as a key building block for drug synthesis.

Applications Driving Demand

The demand for diethyl 2,5-dibromoterephthalate is largely driven by its applications in:

• Organic Electronics: It is a crucial monomer in synthesizing π-conjugated polymers for organic photovoltaics (OPVs) and organic light-emitting diodes (OLEDs). Its structure helps in fine-tuning energy levels and improving charge transport, leading to more efficient devices.
• Material Science: Used in creating ladder-type polyaromatic architectures for blue-light emission and other functional polymers with enhanced thermal and mechanical properties.
• Pharmaceutical Intermediates: As a versatile intermediate, it plays a role in the synthesis of various drug candidates and active pharmaceutical ingredients (APIs), contributing to the development of new therapeutic agents.
• Fine Chemical Synthesis: It serves as a valuable reagent in general organic synthesis for creating a wide array of specialty chemicals.

Key Considerations When Buying

When looking to buy diethyl 2,5-dibromoterephthalate, several factors are crucial for procurement managers:

• Purity: For applications in advanced materials and pharmaceuticals, high purity (typically 97% or 98% minimum) is essential. Ensure the supplier provides certificates of analysis (CoA) detailing purity and impurity profiles.
• Supplier Reliability: Partnering with a reputable manufacturer or supplier in China ensures consistent quality and timely delivery. Look for companies with a proven track record and good customer reviews regarding product quality and service.
• Pricing and Quotation: Obtain competitive quotes from multiple suppliers. Factors like order volume, packaging, and shipping terms will influence the final price. Requesting a sample for evaluation before placing a large order is highly recommended.
• Technical Support: A good supplier will offer technical support, assisting with product specifications, handling, and potential applications.
• Compliance and Documentation: Ensure suppliers can provide necessary documentation, such as Safety Data Sheets (SDS) and Certificates of Origin, especially for international trade.
