62-44-2 Usage

Air & Water Reactions

Insoluble in water.

Reactivity Profile

Phenacetin react with oxidizing agents, iodine and nitrating agents.

Brand name

[Names previously used: Acetophenetidin; Acetphenetidin.].

Side Effects

Long term use may cause renal papillary necrosis and interstitial nephritis, and even induce renal pelvic cancer and bladder cancer. Phenacetin also makes the hemoglobin to form methemoglobin, decreasing blood oxygen carrying capacity, causing cyanosis. In addition, Phenacetin can cause hemolysis and hemolytic anemia, and is toxic to the retina. Long term use may cause also lead to dependence. Countries including America, Britain, German, and Japan have banned Phenacetin, or required packaging to note that it is “not indicated for long-term usage or large doses.”

Fire Hazard

Flash point data for Phenacetin are not available but Phenacetin is probably combustible.

Uses

Analgesic, antipyretic. Component of APC tablets, analgesic mixture also containing aspirin and caffeine. Phenacetin is reasonably anticipated to be a human carcinogen; analgesic mixtures containing Phenacetin are listed as known human carcinogens.

Purification Methods

Crystallise it from H2O or EtOH, and its solubility in H2O is 0.08% (at ~10o) and 1.2% (at ~100o), and in EtOH it is 6.7% (at ~10o) and 36% (at ~100o). Alternatively it can be purified by solution in cold dilute alkali and re-precipitating by addition of acid to neutralisation point. Dry it in air. [Beilstein 13 H 461, 13 IV 1092.]

General Description

Odorless fine white crystalline solid with a lightly bitter taste. Used as an analgesic medicine.

Uses

glycosylation inhibitor

Chemical Properties

white crystalline powder

Mechanisms of Action

On its own, phenacetin has no antipyretic or analgesic effects. In vivo, acetaminophen and paracetamol are metabolized and decomposed to create the antipyretic and analgesic effects. Its decomposites with ammonia and phenyl either not only have no antipyretic and analgesic effects, but also are major factors in its side effects.

Indications and Usage

Phenacetin is mainly used as an antipyretic analgesic, with slow and lasting effects, treating headaches, neuralgia, joint pain, and fever, and weakly resisting rheumatism and inflammation. Because of toxic side effects and the rapid development of similar drugs, however, it is no longer used alone, only as a raw material in combination with other drugs. Commonly combined with aspirin and caffeine to form a less toxic compound aspirin used to treat the common cold. Can make chlorpheniramine cold tablets by adding a small amount of chlorpheniramine to the above compound, used to treat colds with headache, neuralgia, rheumatism, etc. Can be used as a material for organic synthesis or a pharmaceutical intermediate.

Definition
