88-85-7 Usage
Description
4,6-Dinitro-2-sec-butylphenol, also known as Dinoseb, is a chemical compound that is an orange-brown viscous liquid or solid with a pungent odor. It is a derivative of dinitrophenol and can adversely affect the energy-generating reaction in cells, making it highly toxic. Dinoseb was developed by Dow Chemical and marketed in 1948 as a contact herbicide against broadleaf weeds.
Uses
Used in Agricultural Industry:
4,6-Dinitro-2-sec-butylphenol is used as a contact herbicide for post-emergence weed control in cereals, cotton, peas, beans, potatoes, pumpkins, soybeans, and strawberries. It is also used as a plant growth regulator, corn yield enhancer, insecticide, and miticide.
Used in Various Crops:
4,6-Dinitro-2-sec-butylphenol is used as a herbicide in soybeans, a variety of vegetables, fruits, nuts, citrus trees, and other field crops for the control of grasses and broadleaf weeds. It is also used as an insecticide in grapes.
Chemical Properties:
4,6-Dinitro-2-sec-butylphenol is a solid with a pungent odor. It is produced in emulsifiable concentrates or as water-soluble ammonium or amine salts.
Regulatory Status:
Dinoseb was banned for use in the U.S. in 1986 due to potential risks of birth defects and other adverse health effects. It is also banned for use in EU countries and is a U.S. EPA restricted Use Pesticide (RUP). The EPA suspended its registration in 1986, and in August 1990, the EPA banned the burying of dinoseb-contaminated soils in EPA-approved landfills, making incineration the only EPA-approved disposal method. However, incineration is expensive and incomplete, leading to the development of an ex situ soil bioremediation process known as the SABRE process by the Sabre Processing company.
Reactivity Profile
4,6-Dinitro-2-sec-butylphenol is a powerful oxidizing agent. . 4,6-Dinitro-2-sec-butylphenol is dangerously explosive. When not water wet 4,6-Dinitro-2-sec-butylphenol is a high explosive. Dry, the material is easily ignited and 4,6-Dinitro-2-sec-butylphenol will burn very vigorously. On decomposition, nitro compounds such as this emit toxic fumes. Appear to be stable in acid solution, but are susceptible to decomposition by ultraviolet radiation in alkaline solution. [EPA, 1998].
Health Hazard
Extremely toxic: Probable oral lethal dose is 5-50 mg/kg; between 7 drops and 1 teaspoonful for 70 kg person (150 lb.).
Health Hazard
Dinoseb is a highly toxic compound. Theoral LD50 values in small laboratory animals were between 10 and 25 mg/kg. Acutetoxicity tests on daphnids and fathead minnows showed high toxicity. The LC50 values in both these species are 0.24 and0.17 mg/L, respectively (Gersich and Mayes1986). Pregnant white rabbits treated withdinoseb exhibited maternal toxicity above thedose level of 1 mg/kg/day. At highly toxicdose levels, adverse effects were observedin developing fetuses (Johnson et al. 1988).Oral administration of dinoseb producedtumors in lung and liver in mice.
Fire Hazard
This is a dinitrophenol herbicide. (Non-Specific -- Dinitrophenol, Flammable Solid). 4,6-Dinitro-2-sec-butylphenol is dangerously explosive. When not water wet 4,6-Dinitro-2-sec-butylphenol is a high explosive. Dry, the material is easily ignited and 4,6-Dinitro-2-sec-butylphenol will burn very vigorously. On decomposition, nitro compounds such as this emit toxic fumes. Appear to be stable in acid solution, but are susceptible to decomposition by ultraviolet radiation in alkaline solution.

Environmental Fate
Biological. When 14C-labeled dinoseb (5 ppm) was incubated in soil at 25°C for 60 days, 36.0% of the applied amount degraded to 14CO2 (Doyle et al., 1978). Thom and Agg (1975) reported that dinoseb is unlikely to be degraded in conventional sewage treatment processes.Groundwater. According to the U.S. EPA (1986) dinoseb has a high potential to leach to groundwater.Plant. When dinoseb on bean leaves was exposed to sunlight, photodegradation resulted in the formation of persistent, polar compounds. The compounds could not be identified by TLC (Matsuo and Casida, 1970).Chemical/Physical. Reacts with organic and inorganic bases forming water-soluble salts (Worthing and Hance, 1991).Emits toxic fumes of chlorine when heated to decomposition (Sax and Lewis, 1987).
Toxicity evaluation
Dinoseb does not ordinarily persist in the soil, but in storage
areas or locations where it has been spilled, it persists as a soil
and groundwater contaminant. Additionally, release of dinoseb
may result primarily from its use as an herbicide on
a variety of weeds. Release of dinoseb to soil is expected to
result in biodegradation, and dinoseb only weakly adsorbs to
soils and therefore leaches to groundwater. However, it may
bind more strongly to clay soils, especially at acidic pH.
Photolytic degradation of dinoseb from soil surface may be
important. Volatilization is not expected to be significant. In
the absence of volatilization, the half-life of dinoseb in the
sandy loam soil was estimated to be about 100 days. Dinoseb
may photodegrade in surface water with a half-life of 14–18
days. Hydrolysis in water may not be important. It is unlikely to
undergo significant biodegradation in most natural waters.
Volatilization from water is expected to be slow and bioconcentration
is expected to be insignificant. Based on its vapor
pressure of 8.5 × 10-2mmHg at 20 ℃, dinoseb may exist
entirely in the vapor phase in the atmosphere. The half-life for
the reaction of vapor phase dinoseb with photochemically
generated hydroxyl radicals in the atmosphere was estimated to
be 14.1 days. Wet deposition may remove some of the
compound from air.
Check Digit Verification of cas no
The CAS Registry Mumber 88-85-7 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 8 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 88-85:
(4*8)+(3*8)+(2*8)+(1*5)=77
77 % 10 = 7
So 88-85-7 is a valid CAS Registry Number.
