Sulfuric Acid – 96% – ACS & Electronic (Semi) Grade

Sulfuric Acid - 96% - ACS Reagent or Semiconductor Grade

CAS# 7664-93-9

 

DESCRIPTION

 

Sulfuric Acid, ACS Reagent and Semiconductor (Semi) Grade, with the chemical formula H?SO?, is a clear, highly corrosive mineral acid used as a process chemical and laboratory reagent. It appears as a clear, oily liquid (depending on concentration) and is a strong dehydrating and oxidizing agent widely used in chemical manufacturing, research, and industrial processes.

Our Sulfuric Acid is available in two purity grades:

 

• ACS Reagent Grade: Meets ACS reagent specifications for laboratory and analytical use.

 

• Semiconductor (Semi) Grade: Supplied with ultra-low trace element limits for applications requiring minimized contamination.

 

BENEFITS

 

• High Purity Options: ACS Reagent and Semiconductor Grades to meet laboratory and contamination-sensitive requirements.
• Strong Acid & Dehydrating Agent: Effective for a wide range of chemical processes where concentrated acid is required.
• Versatile Industrial & Laboratory Use: Suitable for process chemistry, research, and industrial manufacturing.
• Consistent Quality Controls: Supplied to meet the trace metal and impurity limits shown in the tables below.
