L-Tartrate CAS 36687-82-8

What is L-Carnitine L-Tartrate?

Simply put, this compound is a salt of L-Carnitine and Tartaric Acid.

Standard L-Carnitine base is famous for being incredibly hygroscopic—meaning it pulls moisture from the air rapidly. For a manufacturer, this is a nightmare. It causes clumping in machinery and reduces the shelf-life of the final product.

L-Carnitine L-Tartrate (LCLT) solves this. By combining carnitine with tartaric acid, the resulting powder is stable, pleasant-tasting (slightly acidic/citrusy rather than “fishy”), and absorbs much faster into the body compared to other forms.

Physicochemical Properties

For the R&D team and Quality Control managers, here are the essential specifications you need to know:

Key Application Fields

Why is this specific CAS number requested so frequently? It comes down to versatility.

1. Sports Nutrition & Recovery (The Primary Market) LCLT is the gold standard for muscle recovery. Research suggests it helps reduce muscle tissue damage and soreness (DOMS) after exercise. Because it enters the bloodstream quickly, it is perfect for post-workout powders and capsules.

2. Weight Management Supplements Like all carnitines, it plays a vital role in transporting fatty acids into the mitochondria to be burned for energy. LCLT is often the preferred form for fat burners because it is easy to capsule without anti-caking agents dominating the formula.

3. Functional Beverages Because L-Carnitine L-Tartrate has a pleasant, slightly citrus taste and dissolves easily in water, it is ideal for energy drinks and functional waters where flavor profile is everything.

4. Hair Care and Cosmetics Surprisingly, this ingredient is gaining traction in the personal care industry. It is used in hair follicle treatments to promote energy supply to the hair matrix.

Why Sourcing the Right Quality Matters

When you buy raw materials, you aren’t just buying a chemical; you are buying “run-ability” on your machines.

Low-quality LCLT can still suffer from poor flowability or high moisture content, leading to production downtime. We focus on supplying a crystalline structure that flows freely, ensuring your encapsulation or bottling process runs smooth and fast.

Safety and Precautionary Measures

While L-Carnitine L-Tartrate is generally considered safe and is widely used in food supplements, it is a chemical substance and should be handled with professional care in a manufacturing environment.

• Inhalation: High concentrations of dust may cause respiratory irritation. Always use local exhaust ventilation.
• Skin/Eye Contact: Can cause mild irritation. Operators should wear safety glasses and protective gloves.
• Ingestion: While it is a food supplement, ingestion of pure raw powder in large quantities should be avoided.
• Personal Protective Equipment (PPE): Dust mask (N95 or equivalent), lab coat, and gloves are recommended during weighing and mixing.

Recommended Storage Conditions

To maintain the potency and flowability of the powder, proper storage is non-negotiable.

1. Moisture Control: Even though LCLT is less hygroscopic than the base form, it is still sensitive to humidity. Keep containers tightly closed when not in use.
2. Temperature: Store in a cool, dry place, ideally below 25°C (77°F). Avoid direct sunlight or heat sources.
3. Packaging: It should be stored in original sealed drums (usually 25kg fiber drums) with a double polyethylene inner liner to prevent moisture ingress.
