Note
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.

DescriptionThis compound belongs to the class of organic compounds known as flavonolignans. These are non-conventional lignans that derived from flavonoids. They are characterized by a p-dioxin ring substituted at one carbon atom by a C3C6 (phenylpropan) group and fused to the B-ring of the 2-phenylchromene moiety.
