Cellocidin (2-butynediamide) is an organic chemical compound with the molecular formula C4H4O2N2. This compound was isolated from Streptomyces chibaensis, Streptomyces reticuli and Streptomyces sp. SF-536.

Structure[edit]

Cellocidin is an organic compound containing 4 carbon atoms, 4 hydrogen atoms, 2 oxygen atoms, and 2 nitrogen atoms. It contains one carbon-carbon triple bond between carbons 2 and 3, and two carbon-oxygen double bonds off carbon 1 and carbon 4. 2-butynediamide contains two identical amide groups connected together by the central carbons (carbons 2 and 3).

Safety[edit]

Handling[edit]

Cellocidin should be handled with caution. Wash hands and chemically contaminated clothing thoroughly after handling. Avoid skin and eye contact. Do not ingest or inhale cellocidin. [1]

Storage/disposal[edit]

Cellocidin should be kept in a closed container and stored in a cool, dry place. When disposing, sweep up the chemical and dispose into an appropriate closed-top container. [2]

Exposure[edit]

If swallowed seek medical attention as it may cause bodily damage and most often leads to vomiting and diarrhea. Unnecessary inhalation and skin exposure should be avoided as it may lead to skin and respiratory tract irritation. [2]

Preventative measures[edit]

Eyes: Appropriate protective eye wear should always be worn when working with chemicals.

Skin: Protective gloves and clothing covering all skin should be worn. Avoid clothing that does not fully cover or exposes the skin.

Lungs: Appropriate respirators should be used when working with 2-butynediamide.[2]
