For professionals in the pharmaceutical and fine chemical industries, the ability to efficiently source key chemical intermediates is crucial for project success. CAS 189956-45-4, known chemically as 4-[(4-Hydroxy-2-pyrimidinyl)amino]benzonitrile, is one such compound whose availability and quality directly impact research and manufacturing timelines. This article provides insights for procurement specialists and R&D scientists on how to navigate the market and buy this essential intermediate from reliable manufacturers.

Understanding the Value of CAS 189956-45-4

4-[(4-Hydroxy-2-pyrimidinyl)amino]benzonitrile (C11H8N4O, MW 212.21) is a white powder intermediate, primarily recognized for its application in pharmaceutical synthesis, notably as a precursor for Rilpivirine. Its high purity (often ≥99%) is a critical factor for its effectiveness in downstream reactions, ensuring predictable outcomes in drug development. When you decide to buy this specific CAS number, you are investing in the quality of your final product.

Key Factors for Procurement Managers

Procurement managers constantly balance cost, quality, and supply assurance. When looking to purchase CAS 189956-45-4, consider the following:

  • Supplier Reputation: Investigate the manufacturer's track record, client testimonials, and any certifications they hold. A supplier with a history of consistent quality is invaluable.
  • Product Specifications: Always verify the purity, physical form (e.g., white powder), and molecular details. For CAS 189956-45-4, ≥99% purity is a standard expectation.
  • Pricing and Volume: Obtain quotes from multiple manufacturers to ensure competitive pricing, especially for bulk orders. Understand the pricing structure for different quantities.
  • Logistics and Delivery: Confirm the supplier's shipping capabilities, especially if sourcing internationally from China. Timely delivery is crucial for maintaining production schedules.
