Nitric Acid CAS 7697-37-2
Sinochem is a major Nitric Acid supplier. Meanwhile, our firm staffs a group of experts devoted to your development of China Nitric Acid.
Nitric acid is commonly used as a primary reagent for nitration and oxidation of organic molecules. In organic synthesis, it is also used as a strong oxidizing agent to perform oxidative transformations. In addition, it is used as an intermediate in the production of polyurethanes and polyamides.
- Effectively oxidizes metals and organic compounds, useful in etching and purification.
- Reacts with most metals (except gold and platinum) and is key in metal processing.
- Effective in dissolving impurities and passivating stainless steel.
Nitric acid Description
NAME: Nitric Acid (HNO3)
Molecular Formula: HNO3
Molecular Weight: 63.013
CAS NO.: 7697-37-2
Density: 1.41g/mLat 20°C
Boiling point: 120.5°C(lit.)
Melting point: -42 °C
flashing point: 120.5°C
Appearance: Colorless or yellow fuming liquid
Solubility: Miscible with water.
Properties:
1. Colorless or yellow fuming liquid with a suffocating odor. Forms yellow to brownish-red mist in the air. HNO3 is unstable and decomposes when exposed to light or heat to release nitrogen dioxide, which gives it a light yellow color. Concentrated Colorless or yellow fuming liquid with a suffocating odor. Forms yellow to brownish-red mist in the air. HNO3 is unstable and decomposes when exposed to light or heat to release nitrogen dioxide, which gives it a light yellow color.
2. Concentrated HNO3 is a strong oxidant and can cause combustion when it encounters organic matter, sawdust, etc. Concentrated HNO3 containing trace amounts of oxides can react with almost all metals except aluminum and chromium-containing special steels, while aluminum and chromium-containing special steels can be passivated by concentrated nitric acid. Reacts violently with ethanol, turpentine, coke, and organic debris. is a strong oxidant and can cause combustion when it encounters organic matter, sawdust, etc. Concentrated HNO3 containing trace amounts of oxides can react with almost all metals except aluminum and chromium-containing special steels, while aluminum and chromium-containing special steels can be passivated by concentrated HNO3.

Storage: HNO3 should be handled in a well-ventilated area to avoid inhalation of its vapor. When storing HNO3, keep it away from fire sources and organic matter, store it in a cool, ventilated place, and avoid exposure to sunlight and high temperatures.
Safety Protection: It is a corrosive agent that can cause burns to the skin and eyes. Protective gloves and glasses should be worn. Do not mix with combustibles and reducing agents to avoid fire or explosion.
About Us: With over many years as a certified Nitric Acid manufacturer, we combine innovation with stringent production standards to deliver high-performance product.

Hydrogen nitrate Applications
1. HNO3 is a strong oxidizing acid that corrodes most metals. High concentrated Hydrogen nitrate also have a passivating effect on metals.
2. In the biological wastewater treatment process, nitric acid can be used as a nitrogen source for microbial nutrients.
3. In addition, HNO3 is widely used in the manufacture of fertilizers, chemical fibers, medicines, dyes, rubber, etc. It is also an important analytical chemical reagent that is indispensable for the defense industry, metallurgical industry, printing and dyeing industry and other industrial sectors.
