Use: insecticide, formerly one of the most widely used insecticides in the world; now used in only limited areas because of environmental concerns
Molecular formula: C14H9Cl5
CAS No: 50-29-3
Appearance: colourless to white crystalline powder
Melting point: 108 - 109 C
Boiling point: 260 C
Density (g cm-3): 1.56
Flash point: 165 C
Water solubility: very slight
Stable. Combustible. Incompatible with strong oxidizing agents, iron and aluminium and their salts, alkalies.
Poison if swallowed. May be harmful if inhaled or absorbed through the skin
. Absorption is considerably enhanced by the presence of oils. Possible human carcinogen. Human mutagenic effects
. May cause reproductive damage. May act as a systemic poison. Unlikely to be fatal on its own, but the toxic effects of this chemical appear to be enhanced when exposure simultaneously includes other chemicals.
DDT and its degradation products, particularly DDE, are stored in fat in the body, and this can lead to a total body load of chemical which is potentially much greater than the fatal dose. This stored material is removed only gradually from the body.

(The meaning of any UN hazard codes which appear in this section is given here.)
UN No 2761. Hazard class 6.1. Packing group III.
A serious environmental hazard due to bioaccumulation and transport up the food chain. Concentrations in animals near the top of the food chain (such as predatory birds) may become high enough in areas in which DDT has been heavily used, to have devastating effects upon reproductive ability
Degrades extremely slowly in the environment and is removed very slowly from animal tissue.
Safety glasses, gloves, good ventilation. Treat as a possible carcinogen. Note that use of DDT as an insecticide is banned in most countries.
