3. TOPIC:
Acetaminophen(Paracetamol)

4. Paracetamol:
◦ Paracetamol, also known as acetaminophen, is a medication used to
treat pain and fever. It is typically used for mild to moderate pain
relief. Evidence is mixed for its use to relieve fever. It is often sold in
combination with other medications, such as in many cold
medications.
◦ Formula: C8H9NO2
◦ Molar mass: 151.163 g/mol
◦ Other names: N-acetyl-para-aminophenol (APAP), acetaminophen.
acetaminophen.

5. Spectral analysis:
◦ UV-VIS spectral analysis
◦ IR spectral analysis
◦ H-NMR
◦ C-NMR
◦ Mass spectroscopy

6. UV-VIS ANALYSIS:
UV-Visible spectrum
of the product showed wavelength of maximum
absorbance at 247 nm. The UV-Visible spectrum
of the product obtained was compared with that
of pure paracetamol and gave excellent
similarities.

7. UV-VIS ANALYSIS:

8. IR Analysis:
• The IR spectrum showed sharp peaks at 3360
cm- 1 (N–H stretching)
• A broad peak at 3300 cm-1(O-H stretching)
• 3090 cm-1 (Aromatic C–H stretching)
• 1800cm-1 (=C-H bending)
• 1650 cm-1(C=O stretching)
• 1600 cm-1 (aromatic C=C stretching)
• 1570 cm-1 (N-H bending)
• 1136 cm-1 (C–NH stretching)
