Description
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 H2SO4, 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.

FAQ
What is the CAS-no. and formula of Sulfuric Acid?
Sulfuric Acid is a single-component inorganic acid with the chemical formula H2SO4 and CAS No. 7664-93-9.
What are the synonyms, physical, and chemical properties of Sulfuric Acid?
Sulfuric Acid is a colorless liquid free from suspended matter. ACS Reagent Grade typically has an assay range of 95–98%, while Semiconductor Grade is typically 95.5–97%. The product has very low allowable impurity limits for chlorides, nitrates, phosphates, heavy metals, and trace elements, with tighter controls for Semiconductor Grade material.
What safety precautions should be taken when handling Sulfuric Acid?
Avoid contact with skin, eyes, and clothing and do not breathe vapors or mists. Wear appropriate protective gloves, protective clothing, eye protection, and face protection. Wash thoroughly after handling and remove contaminated clothing before reuse. Seek immediate medical attention if exposure occurs.
What are the appropriate engineering controls for Sulfuric Acid?
Use in well-ventilated areas with corrosion-resistant exhaust ventilation. Local exhaust ventilation is recommended to control acid vapors. Emergency eyewash stations and safety showers should be readily available in handling areas.
