43222-48-6 Usage

Uses

Different sources of media describe the Uses of 43222-48-6 differently. You can refer to the following data:
1. DIFENZOQUAT METHYLSULFATE is Herbicide; agricultural fungicide.
2. DIFENZOQUAT METHYLSULFATE is used to control wild oats in wheat, barley, ?ax, maize, rye grass, vetches and rye grass crops.
3. Difenzoquat Methyl Sulfate could have agricultural uses. It could help reduce downward migration of pesticides in soil/turf to allow it to better target pests.

Safety Profile

Poison by ingestion. Moderatelytoxic by skin contact. When heatedto decomposition it emits very toxic fumes of NOx andSOx.

Environmental Fate

Soil. Though no products were reported, the half-life in soil is approximately 3 months (Hartley and Kidd, 1987).Photolytic. Degrades photolytically to the volatile monomethyl pyrazole (Hartley and Kidd, 1987).Chemical/Physical. May react with aluminum releasing hydrogen (Hartley and Kidd, 1987).

Check Digit Verification of cas no

The CAS Registry Mumber 43222-48-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,3,2,2 and 2 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 43222-48:
(7*4)+(6*3)+(5*2)+(4*2)+(3*2)+(2*4)+(1*8)=86
86 % 10 = 6
So 43222-48-6 is a valid CAS Registry Number.

Method of preparing 1,2-dimethyl-3,5-diarylpyrazolium methylsulfates

-

, (2008/06/13)

A process for the preparation of 1,2-dimethyl-3,5-diaryl-pyrazolium methylsulfates of the formula I STR1 where R1 and R2 independently of one another are hydrogen, C1 -C4 -alkyl, C3 -C8 -cycloalkyl, C1 -C4 -alkoxy, halogen, nitro, C1 -C4 -haloalkyl or aryl all of which are inert under the reaction conditions, in which 1-methyl-3,5-diarylpyrazoles of the formula II STR2 where R1 and R2 have the abovementioned meanings are reacted with a) methanol and SO3, b) methanol and sulfuric acid or optionally, c) methanol and methylsulfuric acid elevated temperatures.

Substituted pyridinesulfonamide compounds or their salts, process for preparing the same, and herbicides containing the same

-

, (2008/06/13)

A substituted pyridinesulfonamide compound or its salt represented by the following general formula (I): wherein R1 is an unsubstituted or substituted alkyl group; R2 is an unsubstituted or substituted alkyl group, or an unsubstituted or substituted alkoxy group; and X and Y are each independently a member selected from the group consisting of alkyl groups and alkoxy groups, is disclosed. This compound is useful as the effective ingredient of a herbicide showing a wide weed-control spectrum even if used in a small amount.
