L-Carnosine | 305-84-0 FAQS

The carnosine chemical structure consists of a dipeptide formed from β-alanine and L-histidine. It features a peptide bond linking the carboxyl group of β-alanine to the amino group of histidine, giving it the molecular formula C9H14N4O3.

The carnosine melting point is approximately 253°C (487.4°F). It decomposes upon further heating, making it unsuitable for applications that require high-temperature stability.

Carnosine solubility is high in water, where it dissolves readily, forming a clear solution. It is practically insoluble in ethanol and other organic solvents, making it best suited for aqueous-based formulations.

The carnosine molecular weight is 226.23 g/mol. This makes it a lightweight compound ideal for use in biological, pharmaceutical, and nutritional formulations.

L-Carnosine is widely used in nutritional supplements and cosmetic formulations due to its antioxidant properties. It is believed to support cellular health, improve skin elasticity, and protect against oxidative stress. It also has potential applications in neuroprotective and anti-aging treatments.
