CAS 110-57-6

trans-1,4-Dichloro-2-butene

VOCCorrosive

This is a toxic chlorinated alkene mainly used to make other industrial chemicals. It matters because workplace or nearby community exposures can irritate and potentially harm health, and it has a cancer concern based on animal data [1][2].

Where It Comes From

Manufactured as a chemical intermediate; releases can occur during production, processing, transport, or disposal [2].

How You Are Exposed

Breathing vapors at work or near facilities, skin contact with liquid, or less commonly via contaminated air or water after spills [1][2].

Why It Matters

Irritates eyes, skin, and lungs; high exposures caused adverse effects in animal studies. IARC classifies 1,4-dichloro-2-butene as possibly carcinogenic to humans (Group 2B) [1][2].

Who Is at Risk

Chemical manufacturing and maintenance workers, transport and lab staff, and people living close to production or storage sites [2].

How to Lower Your Exposure

At work, use closed systems, local exhaust, and chemical-resistant gloves/eye protection; follow monitoring and training. In communities, heed spill/odor advisories and check local emissions reports [2].
