Safety Highlights

4-Bromoanisole does not meet GHS/CLP criteria for classification—no signal word or pictograms required. Nonetheless, exposure precautions, proper handling, and fire safety are important because decomposition or combustion can generate harmful gases.

Flammable Liquid

Direct contact should be avoided; in case of exposure, rinse affected area with plenty of water.

Toxic on Contact

Non-prohibitive extinguishing media include water spray, foam, dry chemical, or CO₂.

Corrosive Agent

Thermal decomposition can release carbon monoxide, carbon dioxide, and hydrogen halides.

Emergency Measures

Rinse immediately with water for at least 15 minutes; seek medical attention.

Proper Storage

Store tightly closed in a dry, cool, well-ventilated area away from strong oxidizers and acids.

Regulatory ID

CAS No: 104-92-7

Environmental Care

Do not allow the chemical to enter drains or the environment. Contain spills and absorb with inert material; dispose of per regulations.

PPE Required

Safety goggles with side protection, chemical-resistant gloves, and protective clothing.

Frequently Asked Questions

Covers 4-Bromoanisole’s non-hazardous classification under GB-CLP, storage guidelines, recommended PPE, spill cleanup steps, and fire safety measures.

Is 4-Bromoanisole classified as hazardous?

No. According to the GB-CLP regulations, it does not meet the criteria for classification, so no hazard pictograms or signal words are required. Standard precautions still apply.

How should 4-Bromoanisole be stored?

Store in a tightly closed container in a cool, dry, well-ventilated area away from strong oxidizers and incompatible substances.

What personal protective equipment is recommended?

Use safety goggles with side shields, chemical-resistant gloves, and protective clothing. In poorly ventilated areas or during large use, a suitable respirator is recommended to avoid inhaling vapors.

What should be done in case of a spill?

Absorb with inert material (e.g., sand, silica gel), keep in suitable closed containers for disposal, and prevent release into the environment or drains. Ensure adequate ventilation during cleanup.

What happens if it is involved in a fire?

Use water spray, foam, dry chemical, or CO₂ to extinguish. Decomposition may release carbon monoxide, carbon dioxide, and hydrogen halides—firefighters must wear self-contained breathing apparatus and full protective gear.
