| General tips | For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months. We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months. Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it. |

| About Packaging | 1. The packaging of the product may be reversed during transportation, cause the high purity compounds to adhere to the neck or cap of the vial.Take the vail out of its packaging and shake gently until the compounds fall to the bottom of the vial. 2. For liquid products, please centrifuge at 500xg to gather the liquid to the bottom of the vial. 3. Try to avoid loss or contamination during the experiment. |

Unusual oxidative transformations of a steroidal 16alpha,17alpha,22-triol.[Pubmed:19857506]
Steroids. 2010 Jan;75(1):70-6.
A number of unexpected reactions were observed during attempts to invert configuration at C16 in 16alpha,17alpha,22-triol 3a. The PDC oxidation of 3a produced the D-seco-aldehyde 4a. Analogous compound 4b was obtained by Swern oxidation of the 16alpha,17alpha-dihydroxy-22-O-TES-ether 3b in addition to the desired 16-ketone 7. The unprotected triol 3a yielded pentacyclic products 5 and 6 under similar conditions. The Mitsunobu reaction of the triol 3a afforded 16-ketone 8 with inverted configuration of the side chain. During heating of a solution of 3a in THF with NaH at reflux autoxidation to the 16-ketone cyclic hemiketal 5, identical to one of the Swern oxidation products, took place.
Five new polyoxygenated cholestane bisdesmosides from the bulbs of Galtonia candicans.[Pubmed:11520229]
J Nat Prod. 2001 Aug;64(8):1069-72.
Two new cholestane bisdesmosides (1, 2) based upon (22S)-cholest-5-ene-3 beta,16 beta,22-triol with an acetyl group at the sugar moiety and three new ones (3-5) based upon (22S)-cholest-5-ene-1 beta,3 beta,16 beta,22-tetrol, along with a known cholestane glycoside, were isolated from the bulbs of Galtonia candicans. The structures of the new compounds were determined by spectroscopic analysis and chemical transformations.
