This is a kind of colorless combustible liquid with strong smell of ammonia, and it is complete soluble in water, ethanol and ethyl ether. And it is sensitive to air and incompatible with strong oxidizing agents, so while keeping, you should keep it under argon in the room temperature.

Being a kind of highly flammable chemical, it may catch fire in contact with air, only needing brief contact with an ignition source, and it has a very low flash point or evolve highly flammable gases in contact with water. Besides, it is corrosive, and it may destroy living tissue on contact. Then it is harmful by inhalation, in contact with skin or if swallowed and it could cause severe burns.

While using this chemical, you should take the following instructions to protece yourself. Keep away from sources of ignition - No smoking and keep in a cool place. Wear suitable protective clothing, gloves and eye/face protection, and if in case of contact with eyes, rinse immediately with plenty of water and seek medical advice; if in case of accident or if you feel unwell seek medical advice immediately (show the label where possible). Lastly, do not empty into drains. You could also refer to WGK Germany  1 to get more safety information.

Diethylamine could be applied in many ways, such as being the analytical reagent and preservative and also be used in making organic synthesis and dyeing. Besides, it could also be as the intermediates, such as for pesticide, such as phosphamidon and pyrimithate, and for herbicide, such as benthiocarb and napropamide. What's more, it could be the solvent and chemical material intermediate to make the medicine, such as procaine, chloroquine, nikethamide, Coraminum and sulfanilamide, and other different fields, such as thiofide, beneficiation reagent, textile assistant, fungicide, corrosion inhibitor, polymerization inhibitor, antifreeze agent and so on.

As to its product categories, there are various, including pharmaceutical intermediates; intermediates of dyes and pigments; chemical synthesis; organic bases; synthetic reagents; essential chemicals; reagent plus; routine reagents; analytical reagents for general use; c-d, puriss p.a.; puriss p.a. And its preparation products are numerous, containing 4-phenyl-1-(p-tolylsulphonyl)piperidine-4-carboxylic acid , montelukast, 4'-iodoacetophenone, 4,6-dimethyl-1h-pyrazolo[3,4-b]pyridin-3-amine, 2-amino-6-methyl-4,5,6,7-tetrahydro-1-benzothiophene-3-carbonitrile, 2-amino-5,6-dihydro-4h-cyclopenta[b]thiophene-3-carbonitrile, 1,4,6-trimethyl-1h-pyrazolo[3,4-b]pyridin-3-ylamine ,97%, 7-(diethylamino)-5-methyl-s-triazolo[1,5-a]pyrimidine, diethylcarbamyl chloride, benzyl cinnamate, 2-amino-4,5,6,7-tetrahydro-1-benzothiophene-3-carbonitrile, 2-amino-4,5-dimethyl-thiophene-3-carbonitrile, 3-(diethylamino)propanoic acid, benzyl salicylate, 5-amino-3-methyl-thiophene-2,4-dicarboxylic acid dimethyl ester, (5-bromo-pyrimidin-2-yl)-diethyl-amine, while its raw material are the etanol, ammonia, hydrogen, 2-ethylaniline, and 2-(ethylamino)ethanol.

Additionally, you could convert the following data information into the molecular structure:
SMILES:N(CC)CC
