Charles Romley Alder Wright several hours and produced a more potent, acetylated form of morphine, now called "diamorphine (or diacetylmorphine)", also known as heroin. After Wright's death, Heinrich Dreser, a chemist at Bayer Laboratories, continued to test heroin. Bayer marketed it as an analgesic and 'sedative for coughs' in 1898. When its addictive potential was recognized, Bayer ceased its production in 1913. In 1892, Wright was the first to report the existence of the stoichiometric intermetallic compound AlSb (aluminium antimonide), which is now recognized as a compound semiconductor with potential use in high-frequency, low-power consumption microelectronics applications, as well as gamma radiation detection.

Analgesic nephropathy Analgesic nephropathy Analgesic nephropathy is injury to the kidneys caused by analgesic medications such as aspirin, phenacetin, and paracetamol. The term usually refers to damage induced by excessive use of combinations of these medications, especially combinations that include phenacetin. It may also be used to describe kidney injury from any single analgesic medication. The specific kidney injuries induced by analgesics are renal papillary necrosis and chronic interstitial nephritis. They appear to result from decreased blood flow to the kidney, rapid consumption of antioxidants, and subsequent oxidative damage to the kidney. This kidney damage may lead to progressive chronic kidney failure,
