Nitric acid 56-58% (CAS 7697-37-2)
The pure compound is colorless, but older samples tend to acquire a yellow cast due to decomposition into oxides of nitrogen and water. Most commercially available nitric acid has a concentration of 68% in water. When the solution contains more than 86% HNO3, it is referred to as fuming nitric acid. Depending on the amount of nitrogen dioxide present, fuming nitric acid is further characterized as red fuming nitric acid at concentrations above 86%, or white fuming nitric acid at concentrations above 95%.
Nitric acid is the primary reagent used for nitration – the addition of a nitro group, typically to an organic molecule. While some resulting nitro compounds are shock- and thermally-sensitive explosives, a few are stable enough to be used in munitions and demolition, while others are still more stable and used as pigments in inks and dyes. Nitric acid is also commonly used as a strong oxidizing agent.

Nitro Thinner 646
Nitro solvent 646 is a classic nitro solvent. Introducing a mixture of various volatile organic liquids (6 components). The original recipe has a ten-year history and has established itself as the most versatile and high-quality composition with excellent properties. Unfortunately now in Europe you will not find a 100% original composition anywhere, as some components are prohibited for circulation in the European Union. Our recipe preserves all the best properties of this product due to the fact that we have replaced the prohibited components with new generation products that are more environmentally friendly. MasterChem has been manufacturing this solvent directly for 25 years. Nitro solvent is a colorless or slightly yellowish liquid with a characteristic odor. It is used in production and in everyday life for diluting and bringing paints and varnishes to a working consistency. If you want to become a sales representative of our product, we are open to negotiations.
