33282-87-0 Usage
General Description
(20S)-3β,16β-Dihydroxypregn-5-ene-20-carboxylic acid γ-lactone, also known as 20-hydroxyecdysone, is a naturally occurring steroid hormone found in plants and insects. It plays a crucial role in regulating growth and development in insects, acting as a molting hormone and controlling the timing of metamorphosis. In plants, it functions as a phytoecdysteroid, with potential beneficial effects on human health, such as anti-inflammatory and antioxidant properties. Additionally, it has been studied for its potential use in agriculture as a biopesticide, due to its ability to disrupt insect development and reproduction. Overall, this chemical compound has diverse and significant roles in both the insect and plant kingdoms, with potential applications in various fields, including medicine and agriculture.
Check Digit Verification of cas no
The CAS Registry Mumber 33282-87-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,2,8 and 2 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 33282-87:
(7*3)+(6*3)+(5*2)+(4*8)+(3*2)+(2*8)+(1*7)=110
110 % 10 = 0
So 33282-87-0 is a valid CAS Registry Number.

Conversion of spirostane and solanidane into pregnane (1) introduction of oxygen function into C-23

A spirosolane derivative possessing a hydroxyl group at C-23, esculeogenin A, a sapogenol of tomato saponin, was found to be easily converted into the corresponding pregnane derivative by refluxing with aqueous pyridine. Therefore, introduction of a hydroxyl group into the C-23 of diosgenin (as representative of spirostane derivatives) and solasodine (as representative of spirosolane derivatives) was attempted by the reaction of NaNO2-BF3 · Et2O. In diosgenin, the objective compound was obtained by the reaction in AcOH. However, in solasodine, we obtained a 23-nitroso derivative by the reaction in AcOH and 23,24-bisnorcholanic acid 22-16 lactone, or vespertilin, in AcOH and CHCl3.
