Butyrobetaine Ethylester Chloride CAS 51963-62-3

Butyrobetaine ethylester chloride CAS 51963-62-3 is a quaternary ammonium salt compound, commonly used as a precursor for L-carnitine synthesis and as a raw material for sports nutrition/metabolic regulation.

Appearance: White crystalline powder, odorless
Solubility: Easily soluble in water; sparingly soluble in nonpolar organic solvents
Stability: Stable at room temperature; requires refrigeration at 2–8℃, protected from light and sealed to avoid moisture absorption and decomposition.

As a key synthetic precursor of L-carnitine, it is converted into L-carnitine through hydrolysis and hydroxylation in vivo/in vitro, participating in fatty acid β-oxidation and energy metabolism.

It is used in the laboratory synthesis of γ-butylbetaine, carnitine derivatives, and related intermediates.

As a metabolic enhancer, it is added to fitness supplements and weight loss products, theoretically improving fat energy supply, exercise endurance, and recovery.

Some products advertise its weight management and cardiovascular health regulation effects (strict compliance is required for use).

It is also used as a quaternary ammonium salt phase transfer catalyst and surfactant intermediate in organic synthesis.
