5-Phenyloxazole-4-carbonyl chloride - Introduction

5-phenyl-1,3-oxazole-4-carbonyl chloride is an organic compound with the chemical formula C10H6ClNO2. It is colorless to yellowish crystals with a strong pungent odor. The compound has a relatively high melting point and boiling point, is insoluble in water, but is soluble in organic solvents such as ethanol and methylene chloride.

5-phenyl-1,3-oxazole-4-carbonyl chloride is mainly used as a reagent in organic synthesis. It can be used in the synthesis of derivatives of phenyl ketones and phenyl acids, as well as in the synthesis of biologically active compounds. It has a wide range of applications in the field of medicine and pesticides.

The method for preparing 5-phenyl-1,3-oxazole-4-carbonyl chloride is generally by adding thionyl chloride to acetic acid, and then adding thionyl chloride and reacting with acetophenone to produce the corresponding aldehyde. Next, the aldehyde and isocyanate chloride are condensed to form the corresponding 2-amino -5-phenyl -1, 3-oxazole, and finally chlorinated to obtain the target product.

Regarding safety information, 5-phenyl-1,3-oxazole-4-carbonyl chloride is an irritant compound. Care should be taken to avoid skin contact and inhalation during operation. Should be operated in a well-ventilated place, wear protective gloves, protective glasses and masks. In case of contact with skin, rinse immediately with plenty of water and seek medical help.
