82560-54-1 Usage
Chemical Properties
Benfuracarb is a thick liquid.
Uses
Different sources of media describe the Uses of 82560-54-1 differently. You can refer to the following data:
1. Benfuracarb is a benzofuranyl methylcarbamate based insecticide used to control aphids, springtails and other pests usually on beet crops.
2. Insecticide.
3. Benfuracarb is a contact and ingested insecticide. It is used to control
insect pests in citrus, maize, rice, sugar beet and vegetables. It is active
against Chrysomelidae, Elateridae, Aphididae, Lissorhoptrus oryzophilus
and Plutella xylostella.
Potential Exposure
A benzofuranyl methylcarbamate
insecticide, nematicide. Not registered for use in the United
States.
Metabolic pathway
When 14C-benfuracarb is applied topically to
houseflies, the houseflies metabolize benfuracarb
easily to form carbofuran which in turn is oxidized at
the 3-position of the ring and N-methyl group, resulting
in further conjugates of the metabolites. Major
metabolites are carbofuran, 3-hydroxycarbofuran, N-
hydroxymethylcarbofuran, 3-ketocarbofuran, 2,3-
dihydro-2,2-dimethyl-3-hydroxybenzofuran-6-ol, 3-
hydroxy-N-hydroxymethylcarbofuran, and 3-keto-N-
hydroxymethylcarbofuran.
Shipping
UN 2992 Carbamate pesticides, liquid, toxic,
Hazard Class: 6.1; Labels: 6.1—Poisonous materials.
Degradation
Benfuracarb is stable in neutral and weakly basic media but unstable in
strongly acidic or basic conditions. It is degraded by sunlight (PM). A
methanolic solution of unlabelled benfuracarb was coated on a glass plate
or applied to soil on a plate and irradiated with a high pressure Hg lamp
(125 W). Details not given were the emission spectrum of the lamp, the
experimental sample temperatures and the irradiation periods. After
irradiation, samples were analysed by TLC methods. The methanol solution
turned a deep brown on irradiation and four major and three minor
products were formed (see Scheme 1). The major products were a cleavage
product (2), the phenol (5) and carbofuran (6). Minor amounts of the
dimeric compounds 3 and 4 were detected. On soil, three photoproducts
were the phenol (5), carbofuran (6) and the cleavage product (7). On a
glass surface four products were the phenol (5), carbofuran (6) and the cleavage products 2 and 7. No products of oxidation were reported (Dureja et al., 1990).
Incompatibilities
Carbamates are incompatible with reducing
agents, strong acids, oxidizing acids, peroxides, and
bases. Contact with active metals or nitrides cause the
release of flammable, and potentially explosive, hydrogen
gas. May react violently with bromine, ketones.
Incompatible with azo dyes, caustics, ammonia, amines,
boranes, hydrazines, strong oxidizers.
Waste Disposal
Do not discharge into drains
or sewers. Dispose of waste material as hazardous waste
using a licensed disposal contractor to an approved landfill.
Consult with environmental regulatory agencies for
guidance on acceptable disposal practices. Incineration with
effluent gas scrubbing is recommended. Containers must be
disposed of properly by following package lab el directions
or by contacting your local or federal environmental control
agency, or by contacting your regional EPA office.
Check Digit Verification of cas no
The CAS Registry Mumber 82560-54-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,5,6 and 0 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 82560-54:
(7*8)+(6*2)+(5*5)+(4*6)+(3*0)+(2*5)+(1*4)=131
131 % 10 = 1
So 82560-54-1 is a valid CAS Registry Number.

Preparation method of carbofuran derivatives
-
Paragraph 0031; 0034; 0037; 0040, (2017/08/29)
The invention discloses a preparation method of carbofuran derivatives. The preparation method of the carbofuran derivatives comprises the following steps: (1) taking amine derivatives and sulfur monochloride as raw materials, adding a first acid-binding agent and a reaction solvent and performing sulfuration reaction to obtain a first intermediate disulfide, wherein the first acid-binding agent is triethylamine and the reaction solvent is chloroform or dichloromethane; (2) performing chlorination reaction on the first intermediate disulfide and chlorine which serve as raw materials to obtain a second intermediate nitrogen and sulfur chloride; (3) taking the second intermediate nitrogen and sulfur chloride and carbofuran as raw materials, adding a second acid-binding agent and performing condensation reaction to obtain the carbofuran derivatives. The preparation method has the advantages that the process is simple, and the product is low in toxicity, high in purity and high in yield.
