For pharmaceutical manufacturers and R&D professionals, sourcing high-quality chiral intermediates is paramount to the success of drug development and production. Diethyl Tartrate (2S,3S), with CAS number 13811-71-7, stands out as a critical building block in this arena. Its specific stereochemistry makes it invaluable for synthesizing enantiomerically pure compounds, which is a non-negotiable requirement in modern pharmaceuticals.

The chemical and physical properties of Diethyl Tartrate (2S,3S) are well-defined, typically appearing as a colorless to light yellow transparent liquid. Crucially, its purity often exceeds 99%, with optical purity also maintaining a high standard, usually above 99%. These specifications are not merely technical details; they directly impact the yield and stereoselectivity of subsequent synthesis steps. A reliable supplier must guarantee these parameters consistently.

The primary utility of Diethyl Tartrate (2S,3S) lies in its role as a chiral intermediate. It is extensively used in the synthesis of chiral drugs, pharmaceutical intermediates, and in the field of asymmetric catalysis. Researchers often employ it in conjunction with transition metals, like titanium, for highly selective epoxidation reactions. This capability allows for the precise construction of complex molecular architectures that are essential for targeted therapeutic actions.

When seeking to purchase Diethyl Tartrate (2S,3S), it is vital to identify reputable manufacturers and suppliers. Companies specializing in fine chemicals and chiral building blocks, particularly those based in China, often offer competitive pricing and a robust supply chain. Looking for suppliers that provide detailed Certificates of Analysis (CoA) and adhere to international quality standards is a wise procurement strategy. Exploring options for bulk purchases can further optimize costs for large-scale manufacturing operations.

For any pharmaceutical company looking to secure a stable supply of this crucial chiral intermediate, engaging directly with established manufacturers is key. Consider requesting quotes from multiple suppliers to compare pricing, delivery times, and technical support. Investing time in supplier qualification ensures that your production runs smoothly and that the integrity of your final pharmaceutical product is maintained. The demand for Diethyl Tartrate (2S,3S) in pharmaceutical R&D continues to grow, making it a strategic raw material to secure.
