L(+)-DMAE Bitartrate: High-Purity Chiral Grade for Advanced Applications

Introduction

L(+)-DMAE Bitartrate (L(+)-Dimethylaminoethanol Bitartrate) is a chiral and highly refined form of DMAE widely used in the pharmaceutical, nutraceutical, personal care, and biochemical industries. Compared with racemic or non-chiral forms, the L(+) stereoisomer offers superior physiological compatibility. As a result, it has become a preferred ingredient in formulations where safety, efficacy, and bioavailability truly matter.

What Makes L(+)-DMAE Bitartrate Different?

Many organic compounds exist in two mirror-image forms known as chiral isomers. The L(+) designation indicates:

• L-form stereochemistry that defines its spatial configuration

• (+) positive optical rotation, meaning it turns polarized light to the right

Because of these characteristics, the L(+) form performs better in applications requiring enhanced biological compatibility. It typically shows:

• Lower gastrointestinal irritation

• Better metabolic compatibility

• Improved stability in sensitive formulations

Key Properties

• Chemical Name: L(+)-Dimethylaminoethanol Bitartrate

• Appearance: White crystalline powder

• Optical Activity: Positive rotation

• Solubility: Highly soluble in water and alcohol

• Grade: High purity with a low impurity profile

Applications

1. Nutraceuticals & Dietary Supplements
L(+)-DMAE Bitartrate plays an important role in cognitive health formulations because it acts as a choline precursor. Additionally, its L(+) configuration improves tolerability and consistency in supplement blends.

2. Pharmaceutical Intermediates
The high chiral purity of the L(+) form supports drug development and synthesis where stereochemical accuracy is essential.

3. Personal Care & Cosmetic Formulations
DMAE derivatives are commonly used in skincare products for toning and firming effects. Furthermore, the L(+) form enhances formulation compatibility and reduces irritation.

4. Biotechnology & Laboratory Use
Its consistent optical and chemical behavior makes it suitable for research applications requiring enantiomer-specific properties.
