L-Theanine (Standard) is the analytical standard of L-Theanine, primarily used for research and analytical applications. L-Theanine (L-Glutamic Acid γ-ethyl amide) is a non-protein amino acid found in green tea leaves. It competitively blocks the binding of glutamate to glutamate receptors (such as NMDA, AMPA, and Kainate receptors) in the brain, exerting neuroprotective, anticancer, and antioxidant activities. L-Theanine can effectively cross the blood-brain barrier and exhibits high oral bioavailability.

Vanillic Acid (Standard) is a reference standard for research and analysis in studies involving Vanillic Acid. Vanillic Acid (Acide vanillique) is used as a condiment in food,which used in wine and vinegar and an intermediate in the production of vanillin from ferulic acid.

Palmitic acid (Standard) is the standard substance of Palmitic acid, and it is applicable for quantitative analysis, quality control, and related research in biochemical experiments. Palmitic acid (Cetylic acid) is a natural product, a common saturated fatty acid found in animals, plants and microorganisms. Palmitic acid has antitumor activity.

Octadecane (Standard) is a reference standard for octadecane, suitable for quantitative analysis, quality control, and biochemical research. Octadecane is an alkane capable of storing thermal energy as a phase change material at ambient temperatures.

Linoleic acid (Standard) is the standard substance of Linoleic acid, and it is applicable for quantitative analysis, quality control, and related research in biochemical experiments. Linoleic acid (9,12-octadecadienoic acid) is a naturally occurring polyunsaturated fatty acid found in animal and vegetable oils. Linoleic acid is an essential fatty acid that is part of membrane phospholipids. Linoleic acid causes damage to red blood cells and hemoglobin through oxidation.
