🧪 Nitric Acid (HNO₃) – High-Purity Industrial & Laboratory Grade

Nitric Acid, chemically known as HNO₃, is a highly corrosive and reactive strong mineral acid used across a wide range of industries including metal processing, chemical synthesis, fertilizers, mining, and laboratories.

Available in concentrations from 55% to 68%, our high-purity nitric acid is produced to meet the demands of industrial, analytical, and laboratory-grade applications, ensuring consistent reactivity and performance.


Key Features & Benefits

  • 🧪 High Purity Formulations
    Available in 55%, 60%, and 68% (concentrated grade) for industrial and lab use.

  • 🛠️ Widely Used in Chemical Processing
    Ideal for etching, pickling, nitration, and oxidation reactions.

  • 🌱 Fertilizer Production
    Main precursor in the synthesis of ammonium nitrate and other agrochemicals.

  • 🪙 Metallurgy & Gold Refining
    Essential in aqua regia preparation for dissolving noble metals (gold, platinum).

  • 🔬 Analytical & Laboratory Use
