Even as a lay person I know that most fluorine molecules are not to be messed with.
- dheera 5y agoUh, except the stuff you shove on your toothbrush? The high-dimensional surface of "threat to life" vs. molecule structure is super, super, non-convex. Like H2O -> yay, H2O2 -> die, H2 + O2 -> fire Like methanol -> die, ethanol -> fun, propanol -> die, butanol -> die, heptanol -> die, octanol -> die
- rakejake 5y agoMy high-school chemistry teacher had this joke: "If you drink Ethanol you dance around people, if you drink Methanol, people end up dancing around you". For context, certain communities in India have people dancing around the funeral procession.
- Cerium 5y agoThe rhyme I was taught: Little Johnny was a chemist, little Johnny is no more. What he thought was H2O was H2SO4.
- ashtonkem 5y agoAnd that’s why I said “most”.
- masklinn 5y ago> Uh, except the stuff you shove on your toothbrush? Fluoride is an exception, only in small quantities, and only topically (lots of salts are toxic, and so are concentrated solutions). By and large fluorine chemistry is a giant pile of nope, so staying away from it is an excellent rule and quite far from a “super, super, non-convex”.
- gpcr1949 5y agoMany marketed small molecules have fluorine in them, organofluorine compounds are sometimes in fact preferred because they are metabolically more stable than the non fluorinated compound. example of some drugs that have more than 1 billion $ sales/year net that contain fluorine: bictegravir,enzalutamide,elexacaftor,paliperidone,sitagliptin,olaparib,teriflunomide.
- FreeFull 5y ago1-Propanol acts like ethanol, but stronger, so you'll be fine if you don't ingest too much. 2-Propanol on the other hand (isopropyl alcohol) gets metabolised into acetone, which isn't great. And the only difference between the two is the way the atoms are arranged!
- amelius 5y agoAcetone is in the breath of people who are on a keto diet.
- netizen-936824 5y agoThat's likely a far lower concentration. The dose makes the poison.
- BeFlatXIII 5y agoHow different is the LD-50 between EtOH and 1-propanol?
- 01100011 5y agoSome amyl alcohol isomers have been investigated as ethanol replacements because of the similar effects, albeit at lower doses, and an absence of a hangover due to less toxic metabolites. They're also commonly found in fermented beverages. Dose makes the poison and all that.
