For procurement managers and R&D scientists in the pharmaceutical and fine chemical sectors, securing a reliable supply of high-purity 4,4'-Cyclohexylidenebisphenol (CAS 843-55-0) is paramount. This white crystalline solid, often referred to as Bisphenol Z, serves as a critical intermediate in numerous synthesis pathways. Understanding its specifications, applications, and how to effectively buy it is key to maintaining production efficiency and product quality.

Understanding 4,4'-Cyclohexylidenebisphenol: Specifications and Applications

The primary allure of 4,4'-Cyclohexylidenebisphenol lies in its high purity, typically assaying at 99.0% or above. This level of purity is indispensable for its role as a pharmaceutical intermediate, ensuring that downstream reactions proceed smoothly and that the final active pharmaceutical ingredients (APIs) meet stringent regulatory requirements. Beyond pharmaceuticals, it also finds use as a general chemical raw material in various organic synthesis processes and potentially in the development of specialty polymers where specific structural attributes are required.

When considering a purchase, look for suppliers that can provide detailed Certificates of Analysis (CoA) confirming purity, physical properties like melting point (190-192 °C), and compliance with international standards such as USP, BP, EP, and FCC. These benchmarks are non-negotiable for companies operating within regulated industries. If you are looking to buy 4,4'-cyclohexylidenebisphenol, prioritizing suppliers who offer these assurances is crucial for risk mitigation.

Navigating the Market: Finding a Reliable Supplier and Manufacturer

The market for 4,4'-Cyclohexylidenebisphenol is served by various manufacturers and suppliers. For B2B procurement, identifying a reputable manufacturer in China, known for its robust chemical production capabilities, can offer significant advantages in terms of both cost-effectiveness and supply stability. When searching for a supplier, consider factors beyond just the price of 4,4'-cyclohexylidenebisphenol. Key considerations include:

  • Manufacturing Capacity and Scalability: Can the supplier meet your current and future volume demands?
  • Quality Control Systems: Does the manufacturer have certified quality management systems (e.g., ISO)?
  • Technical Support: Can they provide expert advice and documentation support?
  • Logistics and Export Experience: Do they have a proven track record in international shipping?

For example, companies seeking to purchase 4,4'-cyclohexylidenebisphenol in bulk should inquire about bulk pricing and delivery timelines. Engaging directly with a manufacturer ensures a more transparent supply chain and potentially better pricing, especially when establishing long-term supply agreements.

Cost-Effectiveness and Inquiry Process

The price of 4,4'-cyclohexylidenebisphenol can vary based on purity, quantity, and market conditions. However, by sourcing directly from manufacturers, buyers can often secure more competitive prices. The inquiry process is typically straightforward: provide your company details, the required quantity, and any specific quality parameters. Reputable suppliers will respond promptly with a quotation and product information, often including sample availability for quality validation. This proactive approach to sourcing helps ensure that your procurement of this essential chemical raw material aligns with both your technical requirements and budget.
