Ethyl methanesulfonate

Ethyl methanesulfonate (EMS) is a chemical compound used in scientific research. It is an alkylating agent and is often used in genetics and molecular biology to induce mutations.

Chemical Properties[edit | edit source]

Ethyl methanesulfonate is a clear, colorless liquid at room temperature. It has a molecular formula of C3H8O3S and a molecular weight of 124.16 g/mol. It is soluble in water and most organic solvents.

Use in Research[edit | edit source]

In genetics and molecular biology, EMS is used as a mutagen. It works by transferring its ethyl group to DNA, causing point mutations. This makes it a valuable tool for researchers studying the effects of mutations on genes and organisms.

Safety[edit | edit source]

EMS is a potent mutagen and is therefore hazardous to handle. It can cause skin and eye irritation, and prolonged exposure can lead to serious health problems. It is classified as a carcinogen by the International Agency for Research on Cancer (IARC).
