Nitrous oxide

Description

Nitrous Oxide, USP, is a colorless gas with the chemical formula N2O and a CAS number of 10024-97-2. It is classified as an oxidizer and is labeled with a warning indicating that it may cause or intensify fire. The gas is stored under pressure and poses a risk of explosion if subjected to heat. Exposure to nitrous oxide may result in drowsiness or dizziness, and it has the potential to displace oxygen, leading to rapid suffocation. Additionally, contact with the gas can cause frostbite. This product is available by prescription only and is distributed by Linde, Inc., located in Danbury, CT 06810-6268, under the Medipure brand. The label includes the designation MDB-0004 (Rev. 01) and should not be removed.
