Description

Bis[(Carboxymethyl)Trimethylammonium] [R-(R*,R*)]-Tartrate is a high-purity, chiral quaternary ammonium salt derivative of tartaric acid. This compound is valued for its role as a versatile chiral phase-transfer catalyst and an intermediate in advanced organic synthesis. It is essential for industries requiring precise stereochemical control, such as pharmaceutical manufacturing for active pharmaceutical ingredients (APIs) and fine chemical production. Our supply ensures consistent quality and reliable availability for critical research and industrial processes.

Application

• Chiral Phase-Transfer Catalyst (PTC) in asymmetric alkylation and other carbon-carbon bond-forming reactions.
• Key Synthetic Intermediate for the preparation of other chiral quaternary ammonium compounds and ionic liquids.
• Pharmaceutical Intermediate in the synthesis of enantiomerically pure drugs and active pharmaceutical ingredients (APIs).
• Asymmetric Synthesis Aid in academic and industrial research for developing new stereoselective methodologies.
• Fine Chemical Production for creating specialty chemicals with defined chirality for agrochemicals and materials science.
• Resolution Agent potential for the separation of racemic mixtures of acids or other compounds.

Quality Control

Every batch of Bis[(Carboxymethyl)Trimethylammonium] [R-(R*,R*)]-Tartrate is produced and tested under a strict quality management system. We provide comprehensive analytical data to confirm identity, purity, and chiral integrity, meeting the stringent requirements for research and cGMP-grade manufacturing. A detailed Certificate of Analysis (COA) is supplied with each shipment, documenting key parameters such as assay, enantiomeric excess, and impurity profiles.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed in a dry environment to prevent absorption of water.
