Could someone explain to me how is it possible to have Clindamycin-HCl(or any other compound in this form)? I wish i had an organic chem txt book although i dont know if i would find it there. Cant find an explanation on the internet. The only way i make sense of it so far is that many organic compounds contian nitrogen which is protonated and then the anion is attached.

Also, does this mean these compounds cannot exist in their "neutral" form? For example can Clindamycin exist on its own or is it always in some salt form? If it can, why is it in the salt form?

Hydrochloride of whatever means just what you guessed - that amine is protonated, so that the molecule has an ionic form and its solubility in water goes up.
