Substance Name: Carbon monoxide [USAN]
RN: 630-08-0
UNII: 7U1EE4V452
InChIKey: UGFAIRIUMAVXCW-UHFFFAOYSA-N
Note
- Carbon monoxide (CO). A poisonous colorless, odorless, tasteless gas. It combines with hemoglobin to form carboxyhemoglobin, which has no oxygen carrying capacity. The resultant oxygen deprivation causes headache, dizziness, decreased pulse and respiratory rates, unconsciousness, and death. (From Merck Index, 11th ed)
