Its preparation method is: adding catechol, 25% sodium hydroxide solution, chloroethane and solvent into autoclave, and then heating to 90 ℃ and then keep 5h, and then have de-solvent, filtering to get the product: 1,2-Diethoxybenzene (2050-46-6).Etherification agent can also be replaced with Dimethyl sulfate , O-p-toluenesulfonate ester , Ethyl iodide , Ethyl bromide and so on, but using of chloroethane as etherification agent, it is better fpr raw materials readily available, inexpensive, low cost, high yield characteristics.

Carcinogenicity of 1,2-Diethoxybenzene (2050-46-6) hasn't been listed as a carcinogen by NTP, IARC,ACGIH, or CA Prop 65. And its toxicological properties have not been fully investigated.

Reported in EPA TSCA Inventory.

An eye irritant. When heated to decomposition it emits acrid smoke and irritating fumes.

 1,2-Diethoxybenzene (2050-46-6) also can be called o-Diethoxy benzene ; Benzene, 1,2-diethoxy- ; Benzene, o-diethoxy- ; Catechol diethyl ether .And it is used as raw materials for pharmaceutical and pesticide.
 1,2-Diethoxybenzene (2050-46-6) is hazardous,so the first aid measures and others should be known.Such as: When on the skin: first,should  flush skin with plenty of water immediatelyfor at least 15 minutes while removing contaminated clothing. Secondly,Get shoesmedical aid .
