Acetonitrile, also known as methyl cyanide, cyanomethane or ethanenitrile, is a highly flammable liquid - therefore Class 3!Acetonitrile is, for instance, used as a solvent in HPLC.

Sodium hydroxide, in its solid phase or in dissolved form, is corrosive and pollutive. Sodium hydroxide is non-flammable, but reacts vigorously upon contact with acids.Hazard label Class 8!

Sodium chloride is common salt and is usually transported in white crystalized form. Sodium is one of the primary electrolytes in the human body. It does not count as a dangerous good.

Tetrahydrofuran is a highly flammable liquid belonging to packaging group II. Risk label Class 3!

Phenol is a flammable solvent which emits toxic gases when heated, and therefore belongs to Class 6.1.

Substances which do not fit the definition of any other class, but pose risks during transport can be classified as Class 9 under UN 3316: Chemical Kit.Please note that the allowed maximum quantity of a test kit is 1 liter or 1 kilogram (inner packaging max. 250 g or 250 ml).

Acetic anhydride, also known as ethanoic anhydride or acetyl oxide, is corrosive, irritating to the eyes and highly flammable. At temperatures of over 49°C, explosive mixtures with air can form. The main hazard is its corrosive effect - hence Class 8!

Acetone is a flammable liquid of Class 3 and carries risk label 3.

Environmentally hazardous substances (UN 3082), liquid substances pollutant to the aquatic environment and solutions or mixtures of such substances belong to Class 9 (Miscellaneous) of the ADR.

Nitrogen is a non-flammable, non-toxic gas and therefore belongs to Class 2.2.In liquid form, it poses risks of frostbite upon contact with skin. Its rapid transition to the gaseous phase at room temperature leads to increased nitrogen concentrations, which can result in oxygen deficiency.
