 sec-Butyl ether (CAS NO.6863-58-7) is also called 0-01-00-00372 (Beilstein Handbook Reference) ; 2,2'-Oxybisbutane ; BRN 1733014 ; Bis(2-butyl)ether ; Di-sec-butyl ether ; Butane, 2,2'-oxybis- . sec-Butyl ether (CAS NO.6863-58-7) is high toxic. It is flammable by fire, heat and oxidants. It will produce toxic spicy smoke stimulation by heat. So the storage environment should be ventilate, low-temperature and dry. Keep sec-Butyl ether (CAS NO.6863-58-7) separate from raw materials of food and oxidants.
