What Is Crotonaldehyde?
Crotonaldehyde (also called 2-butenal) has the formula C₄H₆O and a molar mass of 70.09 g/mol. It is a pale-yellow liquid with a sharp smell that irritates the eyes and nose. It mixes with alcohol and most organic solvents.
The molecule has two reactive spots, a carbon double bond and an aldehyde group, so chemists use it to make many other chemicals. It is flammable, with a flash point around 13 °C, so it can ignite at ordinary room temperature. It is also toxic and irritating.

Where Crotonaldehyde Is Used
- Ethanol denaturant. Added to spirit to make it unfit to drink. Denaturing is regulated, so follow current state excise requirements.
- Sorbic acid and crotonic acid. Used in preservatives, polymers, resins and coatings.
- Fine chemicals and specialty synthesis. A starting point for pharma and agrochemical intermediates.
- Laboratory and research use in organic synthesis.
- Trading and redistribution by chemical dealers.
Many spirit users also add a bittering agent. See our denatonium benzoate and denatonium saccharide pages for Haryana, and our ethyl acetate page if you also buy solvents. The full specification is on our crotonaldehyde product page, and our guide on denaturants for alcohol explains how denaturants work.
Compliance Checklist for Buyers in Haryana
| Area | What to check |
|---|---|
| Storage | Large quantities of flammable liquids may need approval from PESO |

We can’t tell you which approvals your site needs, since that depends on your quantity and activity. Check with your compliance adviser or the authority.
When the Drums Arrive
- Check that drums are sealed, undamaged and labelled with the product name and hazard marks.
- Confirm the grade on the label matches your order.
- Make sure the MSDS and batch details are with the consignment.
- Look for leaks and for a strong vapour smell around the load.
- Unload away from sparks and move drums to the store promptly.
If anything looks wrong, call us before you open or use the material.
Safe Handling and Storage
Crotonaldehyde is flammable, toxic if inhaled or absorbed, and a strong irritant.
- Store drums tightly closed, in a cool, ventilated area away from heat, sparks, oxidisers, acids and bases.
- Earth and bond containers during transfer and use non-sparking tools.
- Avoid breathing vapour. Use local exhaust or a closed system where possible.
- Wear chemical-resistant gloves, splash goggles and suitable respiratory protection.
- Keep a spill kit nearby, and never wash large spills into drains.
- Read the MSDS before anyone handles it.
