(S)-(-)-(3-Chloro-2-hydroxypropyl)trimethylammonium chloride（Cat No.:M011999）is a chiral quaternary ammonium compound with the molecular formula C6H14Cl2NO. It contains a hydroxyl and a chlorine group on the hydroxypropyl chain, which is attached to a trimethylammonium group. This compound is typically used in the synthesis of surfactants, ion-exchange resins, and other specialty chemicals. Its chiral center makes it particularly valuable in stereoselective reactions and applications requiring a specific enantiomer. It is also studied for potential uses in drug delivery systems or as a reagent in organic synthesis, requiring careful handling due to its reactivity.
