Nitrous oxide

Nitrous oxide (CAS 10024-97-2), also known as E942 and commonly referenced as N2O, is a compressed gas used across pharmaceutical manufacturing and food processing as an aerosol propellant and packaging medium. Its rapid solubility and inert behavior under pressure make it a preferred choice where product integrity and contamination control are critical sourcing criteria for industrial and medical applications.

In pharmaceutical manufacturing, nitrous oxide is used as a carrier gas and propellant in metered-dose inhalers and topical aerosol formulations. The food industry relies on this gas as a pressurizing agent. It is used in whipped cream dispensers and other pressurized food-grade packaging, where it dissolves into fat-based products without imparting off-flavors or altering the chemical profile of the contents.

Medical and dental facilities source it as an inhalation analgesic for procedural sedation, requiring pharmaceutical-grade supply with stringent purity documentation and safety certifications for patient use. It also functions as a specialty oxidizer in certain analytical and combustion processes. Nitrous oxide is supplied as a liquefied compressed gas in cylinders and bulk dewars for various volume needs.

Fill quantities range from small laboratory cylinders to large-volume industrial supply. Recognized grades include pharmaceutical (Ph. Eur., USP), food-grade (FCC, E942-compliant), and technical grade. Grade selection directly affects documentation requirements, so buyers should confirm intended application before specifying supply. This ensures compliance with regional safety and quality regulations.
