Product Description

Property

CAS No.: 10102-44-0 Formula: NO2 Molecular Weight: 46.00550

Description

Nitrogen dioxide is the chemical compound with the formula NO 2. It is one of several nitrogen oxides. NO 2 is an intermediate in the industrial synthesis of nitric acid, millions of tons of which are produced each year. At higher temperatures it is a reddish-brown gas that has a characteristic sharp, biting odor and is a prominent air pollutant. Nitrogen dioxide is a paramagnetic, bent molecule with C2v point group symmetry.
