Agricultural Uses
Insecticide is a substance which is toxic to insects and hence used to control them. Insecticides are used where insects cause economic damage or endanger the health of man and his domestic animals.The broad types of insecticides are: (i) Inorganic insecticides: arsenic, lead and copper compounds and their mixtures, the use of which has diminished sharply in recent years because of the development of more effective types that are less toxic to man. (ii) Natural organic compounds: rotenone and pyrethrins (which are relatively harmless to man), nicotine, copper MphtheMte and petroleum derivatives. (iii) Synthetic organic compounds: (a) chlorinated hydrocarbons, such as DDT, dieldrin, endrin, lindane, chlordane and p- dichlorbenzene, (b) organic esters of phosphorus, and (c) imidazole and its derivatives which act on the principle of metabolic inhibition. Besides direct application, these can be fed to growing plants, with the result that the plants can no longer serve as nutrient for the specific insect.There are three main types of insecticides based on their mechanism of action. They are (a) stomach insecticides which are ingested by the insects with their food, (b) contact insecticides which penetrate the cuticle, and (c) fumigant insecticides which are inhaled. Stomach insecticides are used to control chewing insects like caterpillars and sucking insects like aphids. They may be applied to the plant (in anticipation) where they remain active for a considerable time. Polychlorinated biphenyls (PCBs) are added to some insecticides to increase their effectiveness and persistence.Insecticides must be used with considerable caution on food plants or animal forage. For example, arsenic compounds are absorbed by the plant and transported to all its parts. Contact insecticides (like nicotine, demes and pyrethrum), and some synthetic compounds such as DDT and other chlorinated hydrocarbons, organophosphates (Malathion) and carbamates are quickly broken down, and have lasting presence on the plants Highly persistent insecticides may be concentrated in food chains and exert harmful effects on other animals such as birds and fish.
Check Digit Verification of cas no
The CAS Registry Mumber 174060-41-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,4,0,6 and 0 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 174060-41:
(8*1)+(7*7)+(6*4)+(5*0)+(4*6)+(3*0)+(2*4)+(1*1)=114
114 % 10 = 4
So 174060-41-4 is a valid CAS Registry Number.

Synthesis process of indoxacarb
-
Paragraph 0015-0017, (2020/05/30)
The invention discloses a synthesis process of indoxacarb. The method comprises the following steps: reacting m-chlorobenzaldehyde serving as a raw material with malonic acid to remove monomolecular water and carbon dioxide to generate an intermediate SRCA, performing a hydrogenation reduction on the intermediate SRCA in an autoclave in the presence of a catalyst to obtain an intermediate SRCH, and cyclizing the SRCH by using hydrogen fluoride as a dehydrating agent to obtain the final product indoxacarb. The synthesis process is simple and easy to implement, energy is saved, consumption is reduced, the yield is increased, and good economic and environmental benefits are obtained.

9-Fluorenylmethoxycarbonyl was a good protecting group in the field of chemical industry. In the present paper, a new approach for the synthesis of oxadiazine insecticides indoxacarb used 9-fluorenylmethoxycarbonyl as protected group, and triphosgene for chloroformylation. A convenient synthesis of 9-fluorenylmethoxycarbonylhydrazine can be achieved by the nucleophilic substitution reaction of 9-fluorenylmethyl chloroformate and hydrazine hydrate. 4a-Methyl-2-(9-fluorenylmethyl)-7-chloro-indeno [1,2e][1,3,4]oxadia zine-2,4a (3H,5H)-dicarboxylate can be produced via ketone -hydrazine crosslink reaction and cyclization. A preparation of carbamic acid-(chlorocarbonyl)-[(4-trifluoromethoxy) phenyl] me ester can be obtained by the chloroformylation of triphosgene. Finally, the deprotection of 9-fluorenylmethoxy carbonyl and condensation with carbamic acid-(chlorocarbonyl)-[(4-trifluoromethoxy) phenyl] me ester can afford indoxacarb in good yield. A new method for the synthesis of oxadiazine insecticides indoxacarb used 9-fluorenylmethoxycarbonyl-protected group to produce 9-?fluorenylmethoxycarb?onylhydrazine, then through the ketone–hydrazine crosslink reaction, cyclization, deprotection, chloroformylation, and condensation in good yield.
