Gerhard Domagk identified as an antibacterial a red azo dye, introduced in 1935 as the first antibacterial drug, prontosil, soon found at Pasteur Institute to be a prodrug degraded in vivo into sulfanilamide – a colorless intermediate for many, highly colorfast azo dyes – already with an expired patent, synthesized in 1908 in Vienna by the researcher Paul Gelmo for his doctoral research. : A13024 CAS-No 142-04-1 Molecular Formula C6 H7 N . Aromatic amines such as aniline are, in general, much weaker bases than aliphatic amines. G. M. Wójcik "Structural Chemistry of Anilines" in Anilines (Patai's Chemistry of Functional Groups), S. Patai, Ed. 0000206710 00000 n It is also dense, and can be stored for extended periods. 0000262624 00000 n 0000303729 00000 n Specializing in ready to use metabolomics kits. 0000237649 00000 n 0000216382 00000 n 0000247944 00000 n [29] Medications in high demand during World War II (1939–45), these first miracle drugs, chemotherapy of wide effectiveness, propelled the American pharmaceutics industry. 0000315918 00000 n 0000209711 00000 n First, benzene is nitrated with a concentrated mixture of nitric acid and sulfuric acid at 50 to 60 °C to yield nitrobenzene. Traditionally, the weak basicity of aniline is attributed to a combination of inductive effect from the more electronegative sp2 carbon and resonance effects, as the lone pair on the nitrogen is partially delocalized into the pi system of the benzene ring. Aniline and its ring-substituted derivatives react with nitrous acid to form diazonium salts. 0000223400 00000 n 0000275916 00000 n 0000125266 00000 n 0000290391 00000 n endobj In this reaction primary aromatic amine reacts with sodium nitrile and with 2 moles of HCl which is known as Ice cold mixture because the temperature use to be 0.5°C and it forms benzene diazonium salt as major product and water and sodium chloride. 0000240931 00000 n F. F. Runge (1834) "Ueber einige Produkte der Steinkohlendestillation" (On some products of coal distillation), N. Zinin (1842). 0000194258 00000 n 0000286499 00000 n belongs to the class of organic compounds known as aniline and substituted anilines. 0000310729 00000 n ��T��h���������9}9��녜��^ȭ�� $��:��}uG�*��n�i�c6Έ�4���xѧ�����"�9&���.q����=��Xe�U�'UP$��+h�OR״�.Y#C�ت���9�70����&�k��`/�vvEgh�g����@*\�N�꺖���Ο�}_!q �uq�a�Щ=��Xe��-r�>u����5݇�����n�L����$�@Y� ��(e �\��^]�&�W��GƇ� �J��{���:�BIO�W��N8���V���E&������\ͮ��vO!O�eD�DHl��OïbY����W[��?Vs�v`Q,�Mʲs\�kPٱ>��*Л ��㯋2fj tC�{��dV�r��>?�����_(p�&$ua���g`y) 0000315084 00000 n 0000208459 00000 n 0000317186 00000 n 0000212462 00000 n [, Vaziri SA, Hughes NC, Sampson H, Darlington G, Jewett MA, Grant DM: Variation in enzymes of arylamine procarcinogen biotransformation among bladder cancer patients and control subjects. 0000202630 00000 n 0000232697 00000 n 0000282333 00000 n 0000247085 00000 n x���r���3���l����7Grbub;��vڸkiu�ȤLQ�}}�9�� ��b'���� %PDF-1.5 0000208960 00000 n 0000324185 00000 n 0000324459 00000 n 0000293948 00000 n 0000283715 00000 n 2003 Mar;13(3):159-67. For example, sulfonation of aniline produces sulfanilic acid, which can be converted to sulfanilamide. 0000226666 00000 n 0000296613 00000 n 0000313428 00000 n 0000317601 00000 n 0000327364 00000 n 0000241653 00000 n 2 0 obj 0000237305 00000 n 0000038387 00000 n 0000195266 00000 n 0000206573 00000 n 0000318814 00000 n 0000239925 00000 n 0000265073 00000 n These are organic compounds containing an aminobenzene moiety. 0000291221 00000 n 0000251563 00000 n 0000213856 00000 n It reacts with nitrobenzene to produce phenazine in the Wohl-Aue reaction.
