Methanol, also known as hydroxymethane, is an organic compound and the simplest structured saturated monohydrate. Its chemical formula is CH3OH, CAS number is 67-56-1, molecular weight is 32.04, and boiling point is 64.7 ℃. Because it was first discovered in distilled wood, it is also known as "wood alcohol" or "wood essence". The minimum dose for oral poisoning is about 100mg/kg body weight, and ingestion of 0.3-1g/kg can be fatal.
