full_question: In toxicity workups, the level of this molecule can be estimated by multiplying the osmolar gap by a factor of 6.2. This molecule is the larger of the two compounds whose poisoning is counteracted by 4-methylpyrazole, also known as fomepizol. Thiamine and pyridoxine can inhibit the production of this molecule's metabolite oxalic acid. Oxirane is the usual precursor of this molecule in synthetic pathways, such as the Shell-developed OMEGA process. Under acid catalysis, aldehydes react with this molecule to form 1,3-dioxolanes, which is a common strategy for protecting carbonyls using acetals. This compound is reacted with terephthalic acid to produce the thermoplastic polymer PET. In its most common usage, this molecule is often eschewed in favor of its safer relative based on propylene. For 10 points, name this molecule, a simple diol derived from the simplest alkene, that is commonly used in antifreeze.
