4-Nitrobenzyl chloride Property
mp : 71 °C
bp : 112 °C (0.6 mmHg)
BRN : 387187
Stability:: Stable. Incompatible with strong oxidizing agents, bases, amines, moisture, alcohols. Corrodes steel. Reacts slowly with water. Combustible.
Chemical Properties
white to light yellow crystal powde
General Description
Solid.
Air & Water Reactions
May react slowly with water.
Reactivity Profile
Incompatible with sodium hydroxide. [EPA, 1998]. A halogenated aromatic nitro compound. Aromatic nitro compounds range from slight to strong oxidizing agents. If mixed with reducing agents, including hydrides, sulfides and nitrides, they may begin a vigorous reaction that culminates in a detonation. The aromatic nitro compounds may explode in the presence of a base such as sodium hydroxide or potassium hydroxide even in the presence of water or organic solvents. The explosive tendencies of aromatic nitro compounds are increased by the presence of multiple nitro groups.
Health Hazard
Poisonous if swallowed or dust is inhaled.
Fire Hazard
Incompatible with sodium hydroxide.

Quercetin Sources
Quercetin belongs to a class
of water-soluble plant coloring substances called bioflavonoids. Bioflavonoids
have strong antioxidant effects when they are studied in the test tube, and
this is the basis for some of the health claims attached to them. However,
growing evidence suggests that bioflavonoids do not in fact act as antioxidants
in human beings. 24 Nonetheless, as widely available plant substances, they are
considered possible semi-nutrients, substances that are not essential for life
but might help promote optimal health.
Quercetin is not an essential
nutrient. It is found in red wine, grapefruit, onions, apples, black tea, and,
in lesser amounts, in leafy green vegetables and beans. However, to get a
therapeutic dosage, you'll have to take a supplement.
Quercetin supplements are
available in pill and tablet form.
