Question

UV absorbance value of Morphine

• A. 266 nm
• B. 276 nm
• C. 256 nm
• D. 286 nm

Hint:

UV absorbance maxima provide valuable information for drug analysis; morphine's peak at 286 nm is a key identifier.

Answer 1

The Correct Option is D

- Morphine is an opiate alkaloid with a characteristic UV absorption spectrum.
- The maximum UV absorbance (\λ max) for morphine is approximately 286 nm due to the conjugated aromatic ring system in its structure.
- This absorbance is used in qualitative and quantitative analysis of morphine in pharmaceutical preparations using UV-visible spectrophotometry.
- Understanding the UV absorbance helps in drug identification and purity analysis in pharmaceutical quality control.
