2631-40-5 Usage
Description
Isoprocarb, o-cumenyl methylcarbamate
(IUPAC), consists of colorless crystals, which are sparingly soluble in water and are readily soluble in acetone and methanol.
Isoprocarb is produced by reaction of 2-isopropylphenol
with methylisocyanate. Isoprocarb is used for control of
rice, cacao, sugarcane, and vegetable pests.
Chemical Properties
Isoprocarb is a carbamate insecticide. It is a colourless crystalline substance, sparingly soluble in water (0.265g/l) and readily soluble in acetone(400g/l) and methanol (125g/l). It is hydrolysed in alkaline media.The insecticide,with contact and stomach action, effectively controls leafhoppers,plant hoppers and aphids on a variety of crops like rice, cocoa, sugarcane and vegetables. Its residual activity gives effective pest control. It acts by inhibiting cholinesterase.
Uses
Isoprocarb is a non-systematic carbamate insecticide. Isoprocarb functions by reversibly inactivating the enzyme acetylcholinesterase in insects.
Safety Profile
Poison by ingestion,
intravenous, and intraperitoneal routes.
Moderately toxic by skin contact. When
heated to decomposition it emits toxic
fumes of NOx. See also CARBAMATES.
Used for controlling leafhoppers,
planthoppers, and bugs in rice and cacao.
Toxicology
The insecticide isoprocarb is a Class II toxin (moderately hazardous), with the acute oral LD50 among rats being 403-485mg/kg, while the percutaneous LD50 among male rats and mice is>500mg. It is a PAN Bad Actor chemical, since it is a cholinesterase inhibitor. Symptoms of poisoning with this insecticide include muscle weakness,dizziness,salivation,nausea,vomiting,sweating,headache,effects on the CNS and depression. PPE such as splash-resistant safety goggles and chemicalresistant clothing, gloves and masks are advised.
Check Digit Verification of cas no
The CAS Registry Mumber 2631-40-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,3 and 1 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 2631-40:
(6*2)+(5*6)+(4*3)+(3*1)+(2*4)+(1*0)=65
65 % 10 = 5
So 2631-40-5 is a valid CAS Registry Number.

SYSTEM FOR PROTECTING GOODS DURING TRANSPORT
-
, (2013/02/28)
A system for protecting stored goods in a container (10), comprises a cage-like structure (20) formed by at least one pesticide treated net (22), capable of enclosing the stored goods, wherein the cage like structure (20), further comprises means for suspending the pesticide treated nets (14, 28, 30, 32, 34), and means for opening and closing the cage-like structure (26) on at least one section (24) of the at least one net (22). The system is particularly useful for the transport of tobacco, coffee, dried fruits, cocoa, nuts, tea, cereals, vegetables, spices and animals.
One-pot, three-step preparation of alkyl and aryl alkylcarbamates from S-methyl N-alkylthiocarbamates
Artuso, Emma,Degani, Iacopo,Fochi, Rita,Magistris, Claudio
experimental part, p. 1612 - 1618 (2009/04/03)
A general procedure for the synthesis of alkyl and aryl alkylcarbamates starting from the corresponding 5-methyl N-alkylthiocarbamates is described. This procedure consists of three steps that are carried out in a one-pot fashion, without isolating the intermediate N-alkylcarbamoyl chlorides or alkyl isocyanates. All the target products were obtained in high yields (16 examples, average yield 91%). To be noted is the recovery of a co-product of industrial interest, dimethyl disulfide, in a half mole amount for each mole of thiocarbamate, with complete exploitation of the reagent. The alkyl isocyanates, if required, can also be isolated in high yields. Georg Thieme Verlag Stuttgart.
Process for making alkyl N-alkyl or N-aryl-thiocarbamates
-
, (2008/06/13)
A process for the preparation of alkyl esters of N-alkyl or N-aryl thiocarbamic acid having the formula: STR1 wherein R is alkyl or aryl, R2 is alkyl and R1 is hydrogen or alkyl which comprises reacting the S-alkyl ester of N-alkyl or aryl dithiocarbamic acid having the formula: STR2 wherein R, R1, R2 have the meanings stated above with an appropriate alkali metal alkoxide in the presence of one or more alcoholic solvents.
