TCI N0806 Nitric Acid (67%) is an aqueous solution of nitric acid. Nitric acid is one of the most widely used strong mineral acids in the laboratory. It is both a strong acid and a strong oxidizing agent, and this combination makes it important for many kinds of work. These include dissolving metals, digesting samples before elemental analysis, and nitration reactions in organic synthesis. In the TCI catalog, this product belongs to the acids and bases group of synthetic reagents, so it is intended for chemical reactions in research laboratories.
Laboratories choose this material because it can oxidize and dissolve many metals and organic matrices that other acids struggle to break down. The nitrate salts it forms are generally soluble in water. As a result, digested solutions are easy to dilute and analyze with common analytical techniques. In organic synthesis, nitric acid is often combined with sulfuric acid to act as a source of nitronium ions, which introduce nitro groups onto aromatic rings. The concentration printed on the label makes stoichiometric and dilution calculations simpler, which helps keep procedures reproducible.
In Indonesia, nitric acid is needed by analytical chemistry, environmental, mining, metallurgy, food and university laboratories. Analytical and environmental laboratories use it to prepare samples before testing for metals and other elements. Mining and metallurgy laboratories depend on it to dissolve ores, alloys and metal samples. University research groups and teaching laboratories use it for synthesis work and for training students in standard wet-chemistry methods. Because the product comes from a recognized reagent brand, laboratories can document their reagent source consistently.

- Metal dissolution: its combined acidic and strongly oxidizing character lets it dissolve many metals and alloys, and the resulting nitrate salts generally stay soluble in water for further work.
- Sample digestion before elemental analysis: it breaks down organic and inorganic matrices that are hard to handle with other acids, producing solutions that are easy to dilute and analyze.
- Aromatic nitration in organic synthesis: mixed with sulfuric acid, it serves as a source of nitronium ions that introduce nitro groups onto aromatic rings in research-scale synthesis.
- Environmental and food testing preparation: laboratories use it to prepare samples for elemental testing because its oxidizing power helps convert complex sample matrices into clear, measurable solutions.
- Preparing diluted working solutions: the labeled concentration makes stoichiometric and dilution calculations straightforward, so laboratories can prepare consistent working solutions and reproduce procedures reliably across batches.

Nitric acid is corrosive and a strong oxidizer, so it must be handled with care. Keep the container tightly closed in the original acid-resistant packaging or in a compatible container. Store it in a cool, dry, well-ventilated area designated for corrosive acids. Keep it away from organic materials, reducing agents, bases, metal powders and combustible substances. Handle it only in a fume hood while wearing chemical-resistant gloves, safety goggles or a face shield, and a lab coat. When diluting, always add the acid slowly to water, never water to the acid. Keep spill-control materials and an eyewash station nearby. Always consult the supplier's Safety Data Sheet before use and follow local regulations for waste disposal.
