149439-79-2 Usage
Uses
Used in Insecticide Industry:
Spinosyn D aglycone is used as an insecticide for its weak insecticidal properties. Although it is less potent than its parent compound, spinosyn D, it still contributes to the overall effectiveness of the commercial insecticide, Spinosad.
Used in Agricultural and Animal Health Products:
Spinosyn D aglycone is utilized in the development of agro-chemical insecticides and animal health products due to its association with the spinosyns, which are known for their insecticidal properties. However, its weak activity compared to other components in the spinosyn family limits its standalone use in these applications.
Used in Research and Development:
Spinosyn D aglycone serves as a subject of interest in research and development, particularly in understanding the biological activity and environmental impact of spinosyns. Despite its limited insecticidal activity, studying spinosyn D aglycone can provide insights into the structure-activity relationship and potential modifications to enhance its efficacy or explore other applications.
Check Digit Verification of cas no
The CAS Registry Mumber 149439-79-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,4,3 and 9 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 149439-79:
(8*1)+(7*4)+(6*9)+(5*4)+(4*3)+(3*9)+(2*7)+(1*9)=172
172 % 10 = 2
So 149439-79-2 is a valid CAS Registry Number.

Conversion of spinosyn A and spinosyn D to their respective 9- and 17-pseudoaglycones and their aglycones
Creemer, Lawrence C.,Kirst, Herbert A.,Paschal, Jonathan W.
, p. 795 - 800 (2007/10/03)
Forosamine at the 17-position of spinosyns A and D was hydrolyzed under mild acidic conditions to give the corresponding 17-pseudoaglycones. The tri-O-methylrhamnose at the 9-position of the 17-pseudoaglycone of spinosyn A was hydrolyzed under more vigorous acidic conditions to give the aglycone of spinosyn A. However, these conditions led to decomposition of the 17-pseudoaglycone of spinosyn D, presumably due to more facile protonation of the 5,6-double bond to produce a tertiary carbonium ion which undergoes further rearrangements. Spinosyns J and L (3'-O-demethyl spinosyn A and D, respectively) obtained from fermentation of biosynthetically-blocked mutant strains of Saccharopolyspora spinosa, were oxidized to give the corresponding 3'-keto-derivatives and the resultant keto-sugars were then β-eliminated under basic conditions to give the 9-pseudoaglycones of spinosyns A and D respectively. Forosamine at the 17-position of the 9-pseudoaglycone of spinosyn D was then readily hydrolyzed to yield the aglycone of spinosyn D.
