Benfuracarb is a thick liquid.

Benfuracarb is a benzofuranyl methylcarbamate based insecticide used to control aphids, springtails and other pests usually on beet crops.

Insecticide.

A benzofuranyl methylcarbamate insecticide, nematicide. Not registered for use in the United States.

Speed in removing material from eyes and skin is of extreme importance. Eyes: Eye contact can cause dangerous amounts of these chemicals to be quickly absorbed through the mucous membrane into the bloodstream. Immediately and gently flush eyes with plenty of warm or cold water (NO hot water) for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately. Skin: Get medical aid. Dermal contact can cause dangerous amounts of these chemicals to be absorbed into the bloodstream. Wearing the appropriate PPE equipment and respirator for carbamate pesticides, immediately flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Shampoo hair promptly if contaminated; protect eyes. Ingestion: Call poison control. Loosen all clothing. Never give anything by mouth to an unconscious person. Get medical aid. Do NOT induce vomiting. If conscious, alert, and able to swallow, rinse mouth and have victim drink 4 to 8 ounces of water. Check to see if poison control instructs you to use ipecac syrup, otherwise administer slurry of activated charcoal (2 oz in 8 oz of water). If victim is UNCONSCIO United States OR HAVING CONVULSIONS, do nothing except keep victim warm. In some cases you may be specifically instructed by poison control to induce vomiting by way of 2 tablespoons of syrup of ipecac (adult) washed down with a cup of water. Do NOT give activated charcoal before or with ipecac syrup. Inhalation: Get medical aid. Do not contaminate yourself. Wearing the appropriate PPE equipment and respirator for carbamate pesticides, immediately remove the victim from the contaminated area to fresh air. If the victim is not breathing, administer artificial respiration. Do not use mouth-tomouth method if victim ingested or inhaled the substance; give artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. If breathing is difficult, administer oxygen through bag/mask apparatus until medical help arrives. Do not leave victim unattended.

UN 2992 Carbamate pesticides, liquid, toxic, Hazard Class: 6.1; Labels: 6.1—Poisonous materials.

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.

Benfuracarb is a broad spectrum carbamate insecticide and nematicide. It has a low aqueous solubility, is relatively volatile and is not expected to leach to groundwater. It is not persistent in soil or water systems. It has a moderate mammalian toxicity with a low bioaccumulation potential. It is highly toxic to most aquatic organisms, birds and honeybees but slightly less so to earthworms.

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.

ChEBI: Benfuracarb is a carbamate ester, a member of 1-benzofurans and an ethyl ester. It has a role as an EC 3.1.1.7 (acetylcholinesterase) inhibitor, a carbamate insecticide and an agrochemical.

Benfuracarb is synthesised through a three-step chemical process involving key reagents and controlled reaction conditions. The first step uses triethylamine and disulphur dichloride in chloroform at around 5 DegC for 2.5 hours to initiate the formation of the thioether linkage. The second step involves chlorination in chloroform which helps introduce reactive intermediates. Finally, a second treatment with triethylamine in chloroform for 4 hours at similar temperatures completes the synthesis, yielding benfuracarb.

Systemic, stomach and contact action. Acetylcholinesterase (AChE) inhibitor.

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.

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).
