In the complex world of pharmaceutical manufacturing and research, the availability of high-quality chemical intermediates is paramount. One such crucial compound is 5-Bromoquinazolin-6-ylthiourea, identified by CAS Number 842138-74-3. As a dedicated manufacturer and supplier, we understand the stringent requirements that pharmaceutical professionals have for this essential chemical. This article aims to provide a comprehensive overview for R&D scientists and procurement managers looking to buy this compound.

Understanding 5-Bromoquinazolin-6-ylthiourea's Role

5-Bromoquinazolin-6-ylthiourea is primarily recognized for its critical role as a pharmaceutical intermediate. Its molecular structure makes it a key building block in the synthesis of important ophthalmic drugs such as Brimonidine and Brimonidine tartrate. The purity and consistent quality of this intermediate directly impact the efficacy and safety of the final active pharmaceutical ingredients (APIs). Therefore, sourcing from a reliable manufacturer that guarantees high purity (typically ≥98.0%) is non-negotiable.

Beyond its role as an intermediate, this compound also serves as a vital impurity standard. In the pharmaceutical industry, identifying and quantifying impurities is a cornerstone of drug safety and regulatory compliance. 5-Bromoquinazolin-6-ylthiourea is a known impurity of Brimonidine, making it an indispensable reference standard for analytical chemists and quality control departments. Its availability as a precisely characterized standard allows for the validation of analytical methods and ensures that drug products meet strict international guidelines.

Key Considerations When Sourcing

For procurement managers and R&D scientists, selecting the right supplier for 5-Bromoquinazolin-6-ylthiourea involves several considerations:

  • Purity and Assay: Always verify the assay percentage. For pharmaceutical applications, a minimum of 98.0% is often required.
  • CAS Number Verification: Ensure the CAS number 842138-74-3 is correctly listed to avoid product misidentification.
  • Manufacturing Origin: Partnering with established manufacturers, particularly those in regions with strong chemical production capabilities like China, can offer competitive pricing and robust supply chains.
  • Technical Documentation: Requesting Certificates of Analysis (CoA), Material Safety Data Sheets (MSDS), and any relevant regulatory documentation is essential.
  • Supply Chain Reliability: A consistent supply is crucial for ongoing manufacturing processes. Work with a supplier that can demonstrate a stable production capacity and efficient logistics.
