For procurement managers in the pharmaceutical sector, sourcing high-quality raw materials is paramount. D-(+)-Cellobiose (CAS 528-50-7) is one such compound, frequently utilized as a pharmaceutical intermediate. Understanding the critical aspects of purchasing this disaccharide can significantly impact production efficiency and final product quality. This guide is tailored for B2B procurement professionals looking to buy D-cellobiose.

Understanding D-(+)-Cellobiose: The Basics
D-(+)-Cellobiose is a disaccharide composed of two glucose units linked by a β-(1→4) glycosidic bond. Its chemical formula is C12H22O11, and it typically presents as a white crystalline powder with a high purity, often exceeding 98% as verified by HPLC assay. The CAS number, 528-50-7, is a unique identifier essential for accurate sourcing and regulatory compliance. Its solubility in water makes it convenient for various laboratory and industrial processes.

Key Considerations for Buying D-Cellobiose
When looking to purchase D-cellobiose, several factors are crucial for a successful transaction:

• Purity and Quality Assurance: The primary requirement for pharmaceutical intermediates is high purity. Manufacturers should provide detailed Certificates of Analysis (CoA) confirming the assay, appearance, and absence of impurities. For D-cellobiose, an assay of 98% or higher is standard.
• Supplier Reliability: Establishing a relationship with a reputable supplier, ideally a direct manufacturer, is key. A reliable supplier ensures consistent product availability, adherence to delivery schedules, and responsive customer service. Look for suppliers with ISO certifications and a strong track record in the chemical industry.
• Pricing and Bulk Orders: Pharmaceutical companies often require significant quantities. Negotiating competitive D-cellobiose prices, especially for bulk orders, is vital for cost management. Requesting quotes from multiple suppliers can help secure the best market rates.
• Packaging and Storage: Proper packaging, such as sealed bottles or drums, is necessary to maintain the integrity of the D-cellobiose. Storage conditions, typically cool, dry, and protected from light, are also important to prevent degradation.
