Chemical structure

Does anyone know what the . CH3COOH means underneath the structure below?

  • The “·” (dot) denotes a non-covalent association between the main compound and another molecule—in this case, acetic acid (CH₃COOH).
  • This means that one molecule of acetic acid is co-crystallized or co-formulated with the main compound but is not covalently bonded to it.
