L-Theanine, ≥98%

About L-Theanine, ≥98%

L-Theanine is an amino acid derivative carrying the CAS registry number 3081-61-6, specified at ≥98% purity. Its molecular formula is C7H14N2O3 and its molecular weight is 174.2 g/mol. Systematically, it is named (2S)-2-amino-5-(ethylamino)-5-oxopentanoic acid. It is also known as Nγ-Ethyl-L-glutamine or L-Glutamic acid γ-(ethylamide).

In its supplied form it is white to off-white powder or crystals or chunks. Literature values give a melting point of 217-218 °C. Recommended storage is at 2–8 °C, with the container kept tightly sealed. The GHS classification uses the signal word “Warning”, so appropriate gloves, eye protection and ventilation are recommended.

It is commonly used for peptide synthesis, cell culture media and biochemical research. Our customers for this product work in academic and industrial research and diagnostics and biotechnology.

Standard pack sizes are 5 g, 25 g, 100 g and 1 kg, and every batch ships with a Certificate of Analysis (COA) and we export worldwide.
