Hey there! As a supplier of the compound with CAS: 79 - 09 - 4, which is propionic acid, I'm here to spill the beans on its MSDS (Material Safety Data Sheet) information. This stuff is pretty important if you're dealing with propionic acid, whether you're using it in your business or just curious about it.
What's Propionic Acid?
Propionic acid is a clear, colorless liquid with a sharp, unpleasant odor. It's an organic compound that's used in a bunch of different industries. You can find it in food as a preservative, in the production of polymers, and also in various industrial applications.
MSDS Information
1. Identification
First off, let's talk about the basic identification details. The chemical name is propionic acid, and as I mentioned, its CAS number is 79 - 09 - 4. The formula is C₃H₆O₂. It's also known by other names like propanoic acid.

2. Hazards Identification
Propionic acid can be a bit of a troublemaker if not handled properly. It's a corrosive substance. That means it can cause severe burns to the skin, eyes, and respiratory tract. Inhalation of its vapors can lead to coughing, shortness of breath, and even lung damage in severe cases.
When it comes into contact with the skin, it can cause redness, pain, and blisters. If it gets into your eyes, it can cause serious eye damage, including permanent vision loss. So, you definitely want to be careful around this stuff.
3. Composition/Information on Ingredients
The main ingredient in propionic acid is, well, propionic acid itself. Usually, it's available in high - purity forms. For high - purity propionic acid for industrial use, take a look at this link: High - Purity Propionic Acid For Industrial Use.
4. First - Aid Measures
If someone gets propionic acid on their skin, the first thing to do is to immediately flush the affected area with plenty of water for at least 15 minutes. Remove any contaminated clothing while you're at it. If it's in the eyes, flush the eyes with water for at least 15 minutes, lifting the upper and lower eyelids occasionally. Then, get medical help right away.
If someone inhales the vapors, move them to fresh air. If they're not breathing, give artificial respiration. And again, call a doctor as soon as possible.
5. Fire - Fighting Measures
Propionic acid is flammable. Its flash point is around 54 °C (129 °F). In case of a fire, use dry chemical, carbon dioxide, or alcohol - resistant foam to extinguish it. Don't use water directly as it can spread the fire.
Firefighters should wear self - contained breathing apparatus and full protective clothing. And make sure to keep containers cool by spraying them with water if there's a fire nearby.
6. Accidental Release Measures
If there's a spill of propionic acid, the first step is to evacuate the area to avoid exposure to the vapors. Contain the spill if you can, using absorbent materials like sand or vermiculite. Don't let it enter drains or waterways as it can be harmful to the environment.
For large spills, call the appropriate emergency response team. They have the equipment and expertise to handle it safely.
7. Handling and Storage
When handling propionic acid, you need to wear appropriate personal protective equipment (PPE). This includes gloves, goggles, and a lab coat or protective clothing. Make sure to work in a well - ventilated area to prevent the build - up of vapors.
Store propionic acid in a cool, dry place away from sources of heat and ignition. Keep it in tightly sealed containers. And don't store it near strong oxidizing agents or bases as it can react with them.
8. Exposure Controls/Personal Protection
To control exposure, use engineering controls like local exhaust ventilation. This helps to remove the vapors from the air. As for personal protection, in addition to the PPE I mentioned earlier, you might also want to use a respirator if the exposure levels are high.
9. Physical and Chemical Properties
Propionic acid has a boiling point of around 141 °C (286 °F) and a melting point of - 20.8 °C (- 5.4 °F). It's soluble in water, which means it can mix with water easily. Its density is about 0.993 g/cm³ at 20 °C.
10. Stability and Reactivity
Propionic acid is generally stable under normal conditions. But it can react with strong oxidizing agents, bases, and some metals. These reactions can be violent and release heat and potentially dangerous gases.
11. Toxicological Information
Studies have shown that propionic acid can be toxic if ingested, inhaled, or absorbed through the skin. Chronic exposure can cause damage to the liver, kidneys, and respiratory system. It's also a potential irritant and sensitizer.
12. Ecological Information
Propionic acid can be harmful to aquatic life. It can cause oxygen depletion in water bodies if it enters them in large amounts. So, it's important to prevent its release into the environment.
13. Disposal Considerations
When it comes to disposing of propionic acid, follow all local, state, and federal regulations. Don't pour it down the drain or throw it in the trash. You might need to take it to a hazardous waste disposal facility.
14. Transport Information
When transporting propionic acid, it's classified as a hazardous material. It needs to be properly labeled and packaged according to the regulations. Make sure the transport vehicle is equipped to handle hazardous substances safely.
15. Regulatory Information
Propionic acid is regulated by various government agencies. For example, in the United States, it's regulated by the Occupational Safety and Health Administration (OSHA) and the Environmental Protection Agency (EPA). These agencies set standards for its use, handling, and disposal to protect workers and the environment.
