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(2-8C).

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 -20C. Generally, these will be useable for up to two weeks. 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.

Synthetic Studies on the Flavone Derivatives. XII. Synthesis of 2', 3', 5'-and 3', 4', 5'-Trioxygenated Flavones[Reference: WebLink]

METHODS AND RESULTS:
Two unusual flavones, 5,5'-dihydroxy-2', 3', 6', 7-tetramethoxyflavone (1) from Gardenia cramerii and 4',5-Dihydroxy-3',5',6,7-tetramethoxyflavone (6) from Artemisia mesatlantia, and their position isomers were synthesized to investigate the structural correlation in terms of spectral data.
CONCLUSIONS:
The structure of the flavone from G. cramerii is discussed.
