Paracetamol, [a] or acetaminophen, [b] is a non-opioid analgesic and antipyretic agent used to treat fever and mild to moderate pain. [13] [14] [15] It is a widely available over-the-counter drug sold under various brand names, including Tylenol and Panadol.
The concentration in serum after a typical dose of paracetamol usually peaks below 30 mg/L, which equals 200 μmol/L. [45] Levels of 30–300 mg/L (200–2000 μmol/L) are often observed in overdose patients. Postmortem blood levels have ranged from 50 to 400 mg/L in persons dying due to acute overdosage.
References range may vary with age, sex, race, pregnancy, [10] diet, use of prescribed or herbal drugs and stress.

A useful conversion factor is 1 D = 3.335 64 × 10 −30 C m. [8] For diatomic molecules there is only one (single or multiple) bond so the bond dipole moment is the molecular dipole moment, with typical values in the range of 0 to 11 D. At one extreme, a symmetrical molecule such as bromine, Br
