Methanol is well established as being toxic primarily due to its metabolic conversion into formaldehyde and subsequently formic acid, which drives severe metabolic acidosis and organ damage.

The analysis

The retrieved literature consistently supports the toxicological consensus that methanol poisoning is mediated through its metabolic intermediates, formaldehyde and formic acid, which cause severe metabolic acidosis, mitochondrial dysfunction, and tissue damage. Papers [0], [7], and [9] explicitly discuss or utilize this established pathway in the context of clinical toxicity and forensic pathology.
