Description

Nitric Acid- 69-70% - ACS & Electronic (Semi) Grade

CAS# 7697-37-2

DESCRIPTION

Nitric Acid, ACS Reagent and Semiconductor (Semi) Grade, also known as Aqua Fortis or Azotic Acid, is a highly reactive and corrosive liquid used extensively across multiple industries and scientific fields. With a chemical formula of HNO3, this solution is characterized by its clear to pale yellow color and a suffocating, acrid odor.

Our Nitric Acid is available in two purity grades:

ACS Reagent Grade: Meets the American Chemical Society’s rigorous standards for purity, making it suitable for analytical and research applications.

Semiconductor (Semi) Grade: Exceeds the purity requirements of ACS Reagent Grade, providing ultra-high purity levels essential for semiconductor manufacturing processes, where even trace impurities can lead to significant defects.

BENEFITS

High Purity Options: Available in ACS Reagent Grade for general laboratory use and Semi Grade for highly specialized, contamination-sensitive applications like semiconductor manufacturing.
Strong Oxidizing Agent: Effective in a variety of chemical reactions, particularly in oxidation processes, etching, and metal refining.
Versatile Applications: Suitable for diverse uses across scientific research, industrial processing, electronics manufacturing, and more.
Reliable and Consistent Performance: Ensures reliable results in both analytical chemistry and industrial-scale applications.
