Phenacetin-d5(CAS: 69323-74-6)

Phenacetin-d5 is a stable derivative of phenacetin used for nuclear magnetic resonance (NMR) spectroscopy. It has the same structure as phenacetin but with five deuterium atoms substituted for hydrogen atoms.

Phenacetin-d5 is primarily used as an internal standard in NMR spectroscopy to enhance the signal of phenacetin. It is also used for calibrating NMR instruments and in the analysis of phenacetin in various samples.

Phenacetin-d5 itself is generally considered safe for laboratory use. However, it should be handled with care, and users should follow standard safety protocols, including wearing appropriate personal protective equipment and ensuring proper ventilation during use.

Phenacetin-d5 should be stored in a cool, dry place, away from direct sunlight and heat sources. It should be kept in a tightly sealed container to prevent contamination. Refrigeration is not required but may help maintain its stability. Storage at room temperature is recommended for optimal preservation.
