In the vast catalog of chemical compounds, each with its unique identifier, CAS Registry Number (CAS RN), certain molecules stand out for their critical roles in industrial synthesis. CAS RN 86728-85-0, identifying Ethyl (S)-4-Chloro-3-hydroxybutyrate, is one such compound. This chiral molecule serves as an indispensable building block across several high-value sectors, most notably in the pharmaceutical and agrochemical industries, where precision in molecular structure is paramount.

Ethyl (S)-4-Chloro-3-hydroxybutyrate is a bifunctional molecule, featuring both a chloro group and a hydroxyl group on a chiral carbon center, attached to an ethyl ester. This structure grants it significant versatility in organic synthesis, allowing for a range of chemical transformations. Its primary application lies in its use as a chiral precursor for the synthesis of numerous biologically active compounds. In the pharmaceutical realm, it is a key intermediate for drugs targeting metabolic disorders, neurological conditions, and as mentioned in research, even anti-inflammatory and anti-cancer agents.

The demand for compounds with specific enantiomeric configurations, like the (S)-enantiomer of CHBE, has driven the development of efficient synthesis methods. While traditional chemical synthesis can be challenging to control stereoselectivity, biocatalysis has emerged as a highly effective strategy. The use of stereoselective enzymes, such as carbonyl reductases, allows for the production of optically pure CHBE, often with enantiomeric excess (ee) exceeding 99%. This capability is crucial for pharmaceutical applications where product efficacy and safety are directly linked to the stereochemical purity of the active pharmaceutical ingredient (API).

Beyond pharmaceuticals, CAS 86728-85-0 also finds application in the development of agrochemicals. Its structure can be modified to create compounds that target specific pests or plant diseases, contributing to more effective and potentially environmentally friendlier crop protection solutions. Furthermore, it is utilized in biochemical research and as an analytical standard for quality control processes.

For companies looking to buy Ethyl (S)-4-Chloro-3-hydroxybutyrate, it is vital to partner with a reputable CAS 86728-85-0 manufacturer. A reliable supplier will guarantee the purity and stereochemical integrity required for demanding applications. When sourcing this intermediate, consider its role in your specific synthesis and ensure the supplier can provide the necessary quality documentation and potentially scalable production volumes. A well-established chemical supplier in China can often offer competitive advantages in terms of cost and availability for such critical intermediates.

The importance of intermediates like Ethyl (S)-4-Chloro-3-hydroxybutyrate cannot be overstated. They are the silent workhorses that enable the creation of the advanced materials and life-saving drugs we rely on. Understanding their properties and sourcing them from dependable manufacturers is a fundamental step in the modern chemical industry.
