3-Methoxycholestan-2-one is a steroidal ketone compound characterized by the presence of a ketone group at the C-2 position and a methoxy group at the C-3 position of the cholestane skeleton. This molecule is derived from cholesterol and is a key intermediate in the synthesis of various steroidal compounds, including hormones and pharmaceuticals. It plays a significant role in the chemical industry due to its potential applications in the production of corticosteroids, sex hormones, and other biologically active molecules. The structure of 3-methoxycholestan-2-one consists of a cyclohexane ring fused to two six-membered carbon rings, with the ketone and methoxy functionalities providing unique chemical reactivity and properties.

5788-90-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5788-90-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,7,8 and 8 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 5788-90:
(6*5)+(5*7)+(4*8)+(3*8)+(2*9)+(1*0)=139
139 % 10 = 9
So 5788-90-9 is a valid CAS Registry Number.

The Octant Rule VIII. Variable Temperature Circular Dichroism Spectra of α-Methyl- and Methoxyl-Substituted 5α-Cholestan-2- and -3-ones.

Lightner, D. A.,Eng, F. P. C.

, p. 189 - 207 (2007/10/02)

2α- and 2β-methyl- and methoxy-5α-cholestan-3-ones and 3α- and 3β-methyl- and methoxy-5α-cholestan-2-ones have been synthesized and their variable temperature circular dichroism spectra obtained and analyzed.Rotatory strength (R) values for α-axial and equatorial CH3 and OCH3 groups are determined by difference measurements with the parent ketone.The (small) equatorial CH3 R-values do not consistently follow the Octant Rule.Axial OCH3 groups do not obey the Octant Rule ("anti-octant" behavior) and impose a bathochromic shift on the C=O n-?* transition.Equatorial OCH3 groups do not consistently follow octant or "anti-octant" behavior.
