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.

Extractives of jack pine bark: Occurrence of cis- and trans-pinosylvin dimethyl ether and ferulic acid esters.[Reference: WebLink]

METHODS AND RESULTS:
A new natural product, cis-pinosylvin dimethyl ether (3,5-dimethoxy-cis-stilbene) has been isolated from the benzene extract of the bark of jack pine (Pinus banksiana). The only other nonpolar benzenoid extractives isolated were Trans-Pinosylvin dimethyl ether, was alcohol esters of ferulic acid, dehydroabietic acid and related diterpenes, and phlobatannin esters. Data are given also on the wax alcohols, free and esterified wax acids, and n-paraffins.
