In the pharmaceutical industry, the pursuit of drug safety and efficacy is unyielding. A critical component of this pursuit is the precise identification and quantification of impurities. 5-Bromoquinazolin-6-ylthiourea (CAS 842138-74-3) plays a pivotal role in this regard, serving as a highly valued pharmaceutical reference standard. As a dedicated manufacturer and supplier, we understand the critical need for reliable and well-characterized standards for your analytical and quality control operations.

Why is 5-Bromoquinazolin-6-ylthiourea an Important Reference Standard?

5-Bromoquinazolin-6-ylthiourea is recognized as a process-related impurity encountered during the synthesis of Brimonidine, an important ophthalmic drug. Regulatory bodies worldwide, such as the FDA and EMA, mandate strict control over drug impurities to ensure patient safety. Pharmaceutical manufacturers are required to identify, quantify, and manage impurities within specified limits. This is where a precisely characterized reference standard like 5-Bromoquinazolin-6-ylthiourea becomes indispensable.

Having access to a reliable source of this compound allows analytical chemists to:

  • Develop and Validate Analytical Methods: It is essential for creating and validating sensitive analytical techniques (e.g., HPLC, GC-MS) used to detect and quantify this specific impurity in drug substances and finished products.
  • Perform Routine Quality Control: In manufacturing, routine testing against a certified reference standard ensures that each batch of Brimonidine meets the required purity profile.
  • Support Regulatory Submissions: Comprehensive impurity data, supported by reference standards, is a crucial part of dossier submissions to regulatory agencies.

The availability of this compound from a trusted manufacturer means that pharmaceutical companies can secure the necessary materials for their quality assurance programs with confidence. Obtaining a competitive price for these critical standards is often a key consideration for R&D budgets.
