4-Isopropylphenyl Isocyanate CAS 31027-31-3

Introduction

4-Isopropylphenyl isocyanate, CAS No. 31027-31-3, is a colorless to yellow transparent liquid with a pungent odor; its density is 1.01–1.02 g/cm³ (20°C), boiling point 84–85°C (0.5 kPa), flash point 94°C, refractive index 1.52 (20°C), and is soluble in organic solvents such as chlorobenzene.
4-Isopropylphenyl isocyanate decomposes readily upon contact with water. It is prepared by the reaction of 4-isopropylaniline with phosgene and is primarily used as an intermediate in the synthesis of the herbicide isopropylamine. It must be stored in a sealed container under refrigerated conditions (2–8 °C). It is acutely toxic and a skin irritant; safety precautions S23, S26, S36, and S45 must be observed.

4-Isopropylphenyl isocyanate is an intermediate of the herbicide isoproturon.
