89886-42-0 Usage
Description
9(S)-HOT, also known as 9(S)-Hydroxyoctadecatrienoic acid, is a monohydroxy polyunsaturated fatty acid derived from α-linolenic acid through the action of 5-lipoxygenase. It is predominantly found in the cellular ester lipids of Glechoma hederacea leaves and is partially released during artificial dehydration. The biological role of 9(S)-HOT in G. hederacea leaves remains undetermined, but it may be involved in natural senescence.
Uses
Used in Agriculture:
9(S)-HOT is used as a bioactive compound for inhibiting the growth of rice blast fungus, a major pathogen affecting rice crops. It acts as an inhibitor of spore germination and germ tube elongation, with ED50 values of 45 and 30 ppm, respectively. This application helps in protecting rice crops from fungal infections and contributes to improved crop yield and quality.
Check Digit Verification of cas no
The CAS Registry Mumber 89886-42-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,8,8 and 6 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 89886-42:
(7*8)+(6*9)+(5*8)+(4*8)+(3*6)+(2*4)+(1*2)=210
210 % 10 = 0
So 89886-42-0 is a valid CAS Registry Number.

Efficient syntheses of (10E,12Z,15Z)-9-oxo- and (9Z,11E,15E)-13-oxo-octadecatrienoic acids; two stress metabolites of wounded plants

Configurationally pure 9-oxo-10E,12Z,15Z- and 13-oxo-9Z,11E,15E-octadecatrienoic acid are available from linolenic acid via regioselective functionalisation using lipoxygenases from soybean or tomato at specific pH conditions. Reduction of the resulting hydroperoxides followed by oxidation of the resulting allylic alcohols with Bobbitt's reagent yields the configurationally pure but labile ketotrienoic acids 4 and 5 without concomitant isomerisation.
