Ethyl (S)-4-chloro-3-hydroxybutyrate, CAS 86728-85-0, is an optically active aliphatic ester with exclusive S stereoconfiguration. It contains hydroxyl and chloro dual active groups, maintains stable optical activity under common reaction temperatures without racemization. Purified via multi-stage separation, the product delivers consistent batch composition and low residual impurities, widely used in asymmetric synthesis and chiral molecule construction research.

Single stereochemical configuration stays intact below 120 ℃, no structural inversion during heating or derivatization to guarantee stable optical purity of target products.
Terminal hydroxyl and chloromethyl groups support esterification, substitution and ring-closing reactions, enabling flexible multi-step molecular derivation.
Uniformly dissolved in common polar organic solvents; immiscible with water and aliphatic alkane solvents, matching general lab synthetic process systems.
Complete molecular framework reserved under routine reaction heating; long-term exposure above 190 ℃ triggers partial molecular decomposition.
Stable refining process unifies optical performance and impurity levels across batches, reducing experimental deviation in synthetic research.
Balanced reactivity restrains excessive side reactions, elevating yield of chiral target fragments.
Long contact with humid air slightly lowers optical purity, requiring full airtight sealing during transport and preservation.
Slow quality attenuation under cool dry sealed storage, retains stable stereochemical features for long-term reserve.
Store in fully sealed containers inside cool dry shady space. Isolate from high temperature, humid air and strong alkaline substances. Shorten packaging opening duration to minimize moisture contact and protect optical activity.
