Description

(S)-Bis[[[2-(Hydroxyphenyl)-1-Methyl]Ethyl]Ammonium] [R-(R*,R*)]-Tartrate is a high-purity, chiral ammonium tartrate salt of significant importance in advanced organic synthesis and pharmaceutical development. Its value lies in its role as a sophisticated resolving agent or chiral auxiliary for the separation and synthesis of enantiomerically pure compounds. This product is essential for research chemists and process development scientists in the pharmaceutical, agrochemical, and fine chemical industries who require precise stereochemical control.

Application

• As a chiral resolving agent for the separation of racemic mixtures of acids or other functional groups.
• Utilized as a key chiral intermediate or building block in the synthesis of active pharmaceutical ingredients (APIs) with specific stereochemistry.
• Application in asymmetric catalysis as a ligand precursor or catalyst modifier.
• Use in method development and analytical standards for chiral chromatography (HPLC, SFC).
• Research and development of novel agrochemicals and specialty fine chemicals requiring enantiomeric purity.
• Potential use in the preparation of ionic liquids or specialty salts with chiral cations.

Quality Control

Our (S)-Bis[[[2-(Hydroxyphenyl)-1-Methyl]Ethyl]Ammonium] [R-(R*,R*)]-Tartrate is manufactured under strict quality control protocols to ensure high chemical and chiral purity suitable for research and development applications. Each batch is characterized by modern analytical techniques including HPLC, NMR, and optical rotation measurement. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and chiral excess is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after use to prevent absorption of atmospheric moisture, which may affect product stability and performance.
