Common Name

[6a-(hydroxymethyl)-2-(1-methoxy-2-methyl-1-oxopropan-2-yl)-1,4a,4b,9,9-pentamethyl-3,4,5,6,7,8,10,10a,12,12a-decahydro-2h-chrysen-1-yl]acetic acid

Description

2-[6A-(hydroxymethyl)-2-(1-methoxy-2-methyl-1-oxopropan-2-yl)-1,4a,4b,9,9-pentamethyl-1,2,3,4,4a,4b,5,6,6a,7,8,9,10,10a,12,12a-hexadecahydrochrysen-1-yl]acetic acid belongs to the class of organic compounds known as 16-oxosteroids. These are steroid derivatives carrying a C=O group at the 16-position of the steroid skeleton. [6a-(hydroxymethyl)-2-(1-methoxy-2-methyl-1-oxopropan-2-yl)-1,4a,4b,9,9-pentamethyl-3,4,5,6,7,8,10,10a,12,12a-decahydro-2h-chrysen-1-yl]acetic acid is found in Microtropis japonica. 2-[6A-(hydroxymethyl)-2-(1-methoxy-2-methyl-1-oxopropan-2-yl)-1,4a,4b,9,9-pentamethyl-1,2,3,4,4a,4b,5,6,6a,7,8,9,10,10a,12,12a-hexadecahydrochrysen-1-yl]acetic acid is an extremely weak basic (essentially neutral) compound (based on its pKa).
