CAS NO. 1153-85-1, also known as 2-methyl-3-phenyl-3,4-dihydropyran, is a colorless oily liquid that is mainly used as a raw material in the production of pharmaceuticals, flavoring agents and other organic synthesis.


CAS NO. 1153-85-1 is a clear and colorless liquid at room temperature and has a slightly sweet odor and taste. It is slightly soluble in water, but miscible with many organic solvents such as ethanol and acetone. This chemical is widely used as a starting material in the synthesis of various synthetic products such as pharmaceuticals, flavorings and other organic compounds.


CAS NO. 1153-85-1 is synthesized from the reaction of ethyl acetate, methyl alcohol and phenylacetylene. The reaction is carried out in the presence of an acid catalyst, such as sulfuric acid or hydrochloric acid. The product obtained is then purified by distillation or crystallization.


The main application of CAS NO. 1153-85-1 is as a raw material for the synthesis of pharmaceutical, flavorings and other synthetic products. It is also used as a intermediate for the production of 1-hydroxy-2-methyl-3-phenyl-3,4-dihydropyran, which is an important intermediate in the synthesis of resorcinol and its derivatives. Moreover, it is also used as a starting material in the synthesis of certain heterocyclic compounds, such as 3-phenyl-2-methyl-1,2-oxazol-3-one and 3-phenyl-2-methyl-3-hydroxy-3-oxazol-3-one.


CAS NO. 1153-85-1 is toxic when inhaled or swallowed, and is also corrosive to skin, eyes and mucous membranes. Therefore, it should be handled with care and appropriate protective clothing, such as gloves, safety goggles and face masks, should be worn. In addition, CAS NO. 1153-85-1 should be stored in a cool, dry and well-ventilated place and away from incompatible materials, such as acids, alkalis and metal salts.
