||The herbs of Centaurea solstitialis
|Biological Activity or Inhibitors:
|| 1. 5,7-Dimethoxy-2,2-dimethylchromene is a potential inhibitor of juvenile hormone onLocusta migratoria.
||Chloroform, Dichloromethane, Ethyl Acetate, DMSO, Acetone, etc.
||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: email@example.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.

Calculate Dilution Ratios(Only for Reference)
* Note: If you are in the process of experiment, it's need to make the dilution ratios of the samples. The dilution data of the sheet for your reference. Normally, it's can get a better solubility within lower of Concentrations.
5,7-dimethoxy-2,2-dimethylchromene References Information
|Activity of precocene analogs onLocusta migratoria migratorioides (R. and F.)[Reference: WebLink]|
|Several analogs of precocene have been synthesized and evaluated as potential inhibitors of juvenile hormone on Locusta migratoria. Only 5,7-dimethoxy-2,2-dimethylchromene was active; its ED50 and LD50 were measured and compared to those of precocene I and II.
