Dihydrocaffeic acid is a polyphenol with antioxidant, neuroprotective, and enzyme inhibitory properties. Dihydrocaffeic acid scavenges ABTS and 2,2-diphenyl-1-picrylhydrazyl (DPPH) radicals and increases the survival of RGC-5 mouse retinal ganglion cells under hypoxic conditions and in the presence of S-nitroso-N-acetyl-D,L-penicillamine (SNAP). It also decreases endothelial nitric oxide synthase (eNOS) activity and decreases infarct size in a rat model of transient ischemia induced by middle cerebral artery occlusion (MCAO).

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
