Flammable and irritating to eyes, respiratory system, and skin.

Methyl tert butyl ether reagentAlthough structurally simple, it has a wide range of applications:
Organic synthesis: commonly used as an inert solvent for water oxygen sensitive reactions such as Grignard reactions and lithium reagent reactions;
Chromatographic analysis: As a mobile phase component for high-performance liquid chromatography (HPLC) and gas chromatography (GC), it is particularly suitable for the separation of non-polar to moderately polar compounds;
Extraction and purification: used as an extraction solvent in natural product extraction and pharmaceutical intermediate purification, replacing highly toxic chloroform or benzene solvents;
Standard substance preparation: used for the preparation of standard solutions in fields such as environmental testing and petrochemicals;
Teaching experiment: It is commonly used in organic chemistry experiments in universities to demonstrate the properties of ethers and distillation operations.

Methyl tert butyl ether reagentHaving highly flammable and volatile characteristics, proper storage and operation are prerequisites for laboratory safety.Nanjing Chemical ReagentsRemind users to pay attention to the following points:

Keep away from fire and heat sources: store in a cool, well ventilated explosion-proof cabinet with an ambient temperature of ≤ 25 ℃;

Sealing and Light Avoidance: Immediately seal after use to prevent evaporation loss and infiltration of moisture/oxygen in the air;

Do not coexist with strong oxidants such as potassium permanganate, hydrogen peroxide, etc. to prevent combustion or explosion;

Regular testing of peroxides: It is recommended to test them before use after long-term storage, and purify them if necessary;

Operation protection: It is necessary to use it in a fume hood, wear chemical resistant gloves and goggles, and avoid inhaling vapors or skin contact.
