96489-71-3 Usage
Uses
Different sources of media describe the Uses of 96489-71-3 differently. You can refer to the following data:
1. Pyridaben (NC-129, BAS 3001) is widely used as an acaricide with a long residual action and as an insecticide mainly against sucking insects. Trade names include Nexter, Oracle, Poseidon, Pyramite, Sanmite, and Starling.
2. Pyridaben is a pyridazinone derivative used as an acaricide.
Acute Toxicity
Pyridaben shows moderate to low acute toxicity to mammals. The intraperitoneal LDso was 68 mg/kg in male rats (Igarashi and Sakamoto, 1994). The dermal toxicity is low but toxicity by the inhalation route is quite high. With sublethal doses in mice and rats, clinical signs included decreased food consumption, diarrhea, hypothermia, bradycardia, bradypnea, decreased spontaneous motor activity, abnormal gait, prostration, eye closing, amd piloerection. At near lethal or lethal doses (300 mg/kg or more) depression of the central nervous and cardiovascular systems were stronger, but no change occurred in motor functions, including coordination, muscle strength, and neuromuscular transmission, or in sensory functions. Early gastric lavage was effective in presenting poisoning in rats and loperamide was efficacious in reducing the diarrhea that occurred at low doses.
Carcinogenicity
Pyridaben was not oncogenic in typical lifetime feeding studies in the rat and mouse. It is classified by the U.S. Environmental Protection Agency as a Group E compound (no evidence for carcinogenicity to humans).
Neurotoxicity
Pyridaben caused only a low degree of acute neurotoxicity in a standard battery of neurobehavioral tests when given at a single oral dose of 200 mg/kg in males. Effects included piloerection, hypoactiviy, tremors, and lowered body temperature, but these were sporadic and transient. In a longer term (90 day) study in rats, no neurotoxicity or neuropathology was seen at oral doses up to 27 mg/kg/day, but plasma cholinesterase activity was reduced in females.
Environmental Fate and Toxicity
Pyridaben has a low acute toxicity to birds, but it is extremely toxic to aquatic species. Its persistence in soil is relatively brief due to rapid microbial degradation (e.g., the half-life under aerobic conditions is reported to be less than 3 weeks). In natural water in the dark, the half-life is about 10 days, due mainly to microbial action since pyridaben is stable to hydrolysis over the pH range 5-9. The half-life including aqueous photolysis is about 30 min at pH 7 (Tomlin, 2000).

Incompatibilities
Dust may form explosive mixture with
air. Incompatible with oxidizers (chlorates, nitrates, perox-
ides, permanganates, perchlorates, chlorine, bromine, fluo-
rine, etc.); contact may cause fires or explosions. Keep
away from alkaline materials, strong bases, strong acids,
oxoacids, epoxides.
Waste Disposal
It is the responsibility
of chemical waste generators to determine the toxicity and
physical properties and of a discarded chemical and to
properly identify its classification and certification as a haz-
ardous waste and to determine the disposal method. United
States Environmental Protection Agency guidelines for the
classification determination are listed in 40 CFR Parts
261.3. Additionally, waste generators must consult and
follow all regional, national, state and local hazardous
waste laws to ensure complete and accurate classification
and disposal methods. Follow recommendations for the
disposal of pesticides and pesticide containers. Containers must be disposed of properly by following package
label 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 96489-71-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,6,4,8 and 9 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 96489-71:
(7*9)+(6*6)+(5*4)+(4*8)+(3*9)+(2*7)+(1*1)=193
193 % 10 = 3
So 96489-71-3 is a valid CAS Registry Number.

Nickel-catalyzed oxidative dehydrogenative coupling of alkane with thiol for C(sp3)-S bond formation
Liu, Shengping,Jin, Shengnan,Wang, Hao,Qi, Zaojuan,Hu, Xiaoxue,Qian, Bo,Huang, Hanmin
, (2021/03/15)
A nickel-catalyzed oxidative dehydrogenative coupling reaction of alkane with thiol for the construction of C(sp3)-S bond has been established, affording more than 50 alkyl thioethers. Notably, pharmaceutical and agrochemicals, such as Provigil, Chlorbenside and Pyridaben, were readily synthesized by this approach. The sterically hindered ligand BC and disulfide which was formed in situ oxidation of thiol, efficiently avoiding nickel-catalyst poisoning. A set of mechanistic experiments disclose both Ni-catalyzed and Ni-free HAA processes.
