For researchers and procurement specialists in the chemical and pharmaceutical industries, the reliable sourcing of high-quality building blocks is non-negotiable. Fmoc-D-Glu(OtBu)-OH (CAS 104091-08-9) is one such critical intermediate, widely used in peptide synthesis and pharmaceutical development. This guide aims to assist buyers in making informed decisions when looking to buy this essential compound.

The first step in sourcing Fmoc-D-Glu(OtBu)-OH is to identify reputable manufacturers and suppliers. Many companies offer this product, but it is crucial to vet them for quality assurance, production capacity, and consistency. When evaluating potential partners, pay close attention to their product specifications, such as purity (often stated as ≥98.0% by HPLC), appearance, and specific optical rotation. A Certificate of Analysis (CoA) should always be requested to verify these details for each batch.

Understanding the market dynamics, including the price of Fmoc-D-Glu(OtBu)-OH, is also a key aspect of procurement. Prices can vary significantly based on the supplier, the quantity ordered, and the prevailing market conditions. Buyers often look for suppliers in China, as they frequently offer competitive pricing and large-scale production capabilities. However, it is essential to balance cost-effectiveness with unwavering quality and reliable delivery.

When considering a long-term supply agreement, assessing a supplier's ability to consistently meet demand is vital. Factors such as production lead times, packaging options (e.g., 1g, 5g, 25g, 1kg), and shipping logistics should be thoroughly reviewed. A responsive and transparent supplier relationship is key to avoiding disruptions in research or production timelines.

For those needing Fmoc-D-Glu(OtBu)-OH for demanding applications, exploring suppliers who also offer technical support and custom synthesis services can be advantageous. This can facilitate process optimization and troubleshooting. Ultimately, a successful procurement strategy involves a thorough evaluation of product quality, supplier reliability, and competitive pricing to ensure the best value and support for your project needs.
