Storage conditions
1. Storage precautions shall be stored in a cool and ventilated warehouse. Keep away from fire and heat. The storage temperature should not exceed 37℃. Keep container sealed. Should be separated from oxidizing agents, acids, metal powder, etc., avoid mixed storage. Explosion-proof lighting and ventilation facilities are adopted. Prohibit the use of mechanical equipment and tools that can easily produce sparks. The storage area should be equipped with leakage emergency treatment equipment and appropriate storage materials.

2. Packed in white iron drum, the net weight of each is 180kg. Storage in a cool and ventilated place, according to the provisions of inflammable and toxic chemicals.

The stability of
1. Chemical properties: similar to 2- (diethylamino) ethanol. Can produce hexachloroplatinate 2C4H11NO·H2PtCl6 (melting point 178℃), perchlorate C4H11NO·HClO4 (melting point 400℃), tetrachloroaurate C4H11NO· HaUCl4 (melting point 194℃).

2. This product has low toxicity. It has a stimulating effect on skin and central nervous system. Therefore, protective measures should still be taken in accordance with the "toxic chemicals regulation".
