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.
Need more advice on solubility, usage and handling? Please email to: service@chemfaces.com
The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.

Efficient total syntheses of phytoalexin and (+/-)-paniculidine B and C based on the novel methodology for the preparation of 1-methoxyindoles.[Pubmed:
15202897]
METHODS AND RESULTS:
A general route to 2-unsubstituted-1-methoxyindoles, based on our methodology for the synthesis of 1-methoxyindoles, is reported. This synthesis renders accessibility to a variety of natural products possessing the said skeleton. A direct synthesis of phytoalexin (1), (+/-)-Paniculidine B (2), and (+/-)-paniculidine C (3) is disclosed based on the methodology.
CONCLUSIONS:
The synthesis of Paniculidine B (2) has been achieved from aldehyde 10 in only two steps in 88% yield and in five steps from a methoxyindole compound 8 obtained using our earlier methodology.

Structures of paniculidines A and B: novel prenylindoles from Murraya paniculata[Reference:
WebLink]
METHODS AND RESULTS:
Two new indoles named Paniculidine A and Paniculidine B were isolated from Murraya paniculata (Linn.) Jack., and their structures have been elucidated as methyl 2-methyl-4-(indol-3-yl)-butyrate and 2-methyl-4-(1-methoxyindol-3-yl)-1-butanol, respectively.
