| Hazard Information | Back Directory | [General Description]
White crystals in commerce, a brown or dark brown liquid. | [Reactivity Profile]
Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. | [Air & Water Reactions]
Insoluble in water. | [Potential Exposure]
2,4-Dichlorophenoxyacetic acid,
was introduced as a plant growth-regulator in 1942. It
is registered in the United States as a herbicide for control
of broadleaf plants and as a plant growth-regulator. Thus,
workers engaged in manufacture, formulation or application
are affected, as may be citizens in areas of application. The
Vietnam war era defoliant, Agent Orange, was a mixture of
2,4-D and 2,4,5-T. | [Fire Hazard]
This chemical is combustible. | [First aid]
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately
with soap and water. Seek medical attention immediately.
If this chemical has been inhaled, remove from exposure,
begin rescue breathing (using universal precautions, includ-
ing resuscitation mask) if breathing has stopped and CPR
if heart action has stopped. Transfer promptly to a medical
facility. When this chemical has been swallowed, get
medical attention. Give large quantities of water and induce
vomiting. Do not make an unconscious person vomit. | [Shipping]
UN3345 Phenoxyacetic acid derivative pesticide,
solid, toxic, Hazard Class: 6.1; Labels: 6.1-Poisonous
materials. A DOT regulated marine pollutant. | [Incompatibilities]
A weak acid, incompatible with bases.
Decomposes in sunlight or heat, forming hydrogen chloride
and phosgene. Contact with strong oxidizers may cause fire
and explosions. | [Chemical Properties]
2,4-Dichlorophenoxyacetic acid is a white
to yellow crystalline powder with a slight phenolic odor. | [Waste Disposal]
Incineration of phenoxys is
effective in 1 second @ 982
C, using a straight combustion
process or @ 482℃
using catalytic combustion. Over 99%
decomposition was reported when small amounts of 2,4-D
were burned in a polyethylene bag. See “References”
for additional detail. In accordance with 40CFR165, follow
(31); recommendations for the disposal of pesticides and
pesticide containers. Must be disposed properly by follow-
ing (100) Package (2) label directions or by contacting
your local or federal environmental control agency, or by
contacting your regional EPA office. Consult with environ-
mental regulatory agencies for guidance on acceptable
disposal practices. Generators of waste containing this
contaminant (≥100 kg/mo) must conform with EPA regu-
lations governing storage, transportation, treatment, and
waste disposal. | [Uses]
2,4-D isooctyl ester is a useful biochemical for proteomics research. | [Production Methods]
Commercial production of 2,4-D-isoctyl would have followed the same industrial pathway used for other ester derivatives of 2,4-D, although specific data for this variant are limited. Production begins with large scale synthesis of 2,4-D acid, which is then esterified with isooctyl (branched C8) alcohol under controlled temperature and solvent conditions to form the isooctyl ester. | [Mechanism of action]
Selective, systemic, absorbed through roots and increases biosynthesis and production of ethylene causing uncontrolled cell division and so damages vascular tissue. Synthetic auxin. | [Toxics Screening Level]
The interim initial threshold screening level (ITSL) for 2,4-D IOE is 3 μg/m3 based on an annual averaging time. | [Pesticide Type]
