Chemical informatio​n and the Jan 2014 West Virginia Elk River chemical release

From TOXNET:

You may be aware from multiple news sources that little information was available about 4-methylcyclohexanemethanol at the time of the spill in West Virginia’s Elk River earlier this month. Since the spill, government and private sector scientists have contributed to collecting and verifying information about the chemical. As a result, there is now a page on the Centers for Disease Control (CDC) website about the chemical and the methodology used by CDC to develop its recommendations.

There is also a new record in the NLM Hazardous Substances Data Bank (HSDB) for the chemical 4-Methylcyclohexanemethanol, which has a Chemical Abstracts Service registry number (CASRN) of 34885-03-5. Other terms for the spilled substance are “MCHM” or “crude MCHM” or “4-Methylcyclohexane methanol.”

Please note that in some social media and early news reports, the chemical was MISIDENTIFIED as Methylcyclohexanol (CASRN: 25639-42-3). This is NOT the correct chemical. In chemical incidents, it is unusual for little online information to be available about a substance. Chemicals can often be readily identified using online resources such as TOXNET and WISER. In the absence of published information, local and state officials request consultation with local, state, federal and industry experts. Typically, following such an incident there is immediate, ongoing, extensive consultation and communication among responders and experts to determine appropriate actions. When planning for providing health information following chemical incidents, it is critical for institutions and government agencies to know who to contact in uncommon situations as well as knowing the authoritative published sources of chemical information.
