Phenacyl bromide is the organic compound with the formula C 6 H 5 C(O)CH 2 Br. This colourless solid is a powerful lachrymator as well as a useful precursor to other organic compounds. It is prepared by bromination of acetophenone: [2] C 6 H 5 C(O)CH 3 + Br 2 → C 6 H 5 C(O)CH 2 Br + HBr. The compound was first reported in 1871. [3]
Another example is Bex, a once popular Australian compound analgesic which is no longer sold. It contained 42% aspirin, 42% phenacetin, plus caffeine. [2]The United States Food and Drug Administration also now requires that manufacturers of compound analgesics unequivocally state each ingredient's purpose.
The combination was first introduced as the name Trigesic, as the formula of 125 mg paracetamol, 230 mg aspirin, and 30 mg caffeine, in July 1950 by Squibb, which is now Bristol Myers Squibb, but was recalled in the following year due to several reports that the drug might cause blood dyscrasia.

In organic chemistry, a phenacyl group is an aromatic substituent that consists of a phenyl group attached to an acyl group. A molecule containing a phenacyl group has the formula RCH 2 (CO)C 6 H 5 and the structure shown to the right. Here, R denotes the remainder of the molecule; for instance, if R is Br, then the compound could be called ...
Salicylamide is used in combination with both aspirin and caffeine in the over-the-counter pain remedy PainAid. It was also an ingredient in the over-the-counter pain remedy BC Powder but was removed from the formulation in 2009, and Excedrin used the ingredient from 1960 to 1980 in conjunction with aspirin , acetaminophen , and caffeine .
4-686-293-01, also known as Agent 1-10, is a highly potent experimental carbamate nerve agent, patented in May 1967 by the US army. [1] Due to its high molecular weight and thermal stability, it can remain embedded within various surfaces and clothes for prolonged periods of time.
EA-3834 is a potent anticholinergic deliriant drug with a fairly long duration of action, related to the chemical warfare agent 3-quinuclidinyl benzilate (QNB). It was developed under contract to Edgewood Arsenal during the 1960s as part of the US military chemical weapons program, during research to improve upon the properties of earlier agents such as QNB.
