The invention relates to salts formed between basic H2-receptor antagonists and a complex of bismuth with a carboxylic acid, and solvate of such salts, excluding salts in which the basic H2-receptor antagonist is ranitidine. Examples of suitable carboxylic acids are citric acid and tartaric acid....

22. Carboxylic Acid Derivatives: NAS Video LessonsWorksheetPractice AI Tutor Topic summary Created using AI Carboxylic acids can be named using the IUPAC system orcommon names. In IUPAC, replace thealkanesuffix with "oic acid." Common names, often historical, include formic (1 carbon), ac...
22. Carboxylic Acid Derivatives: NAS Video LessonsWorksheetPractice AI Tutor Topic summary Created using AI Carboxylic acids can be transformed into various derivatives, includingacid chlorides,amides, and nitriles. Acid chlorides, the most reactive acyl compounds, are typically synthesized ...
( Nomenclature, Structure, Physical and spectrum properties of acid derivatives) 14.1.1 羧酸衍生物的命名 1. 酰卤(RCOX,acyl halide): RCOX,从结构上看是羧酸与 HX 形成的酸酐,以酰基的卤化物命名,称某酰卤。如: CH3COCl CH3CH2CHCOBr PhCOCl O Br CCl 1 有机化学电子教案 第十四章 羧酸...
Hydrolysis of Carboxylic Acid Derivatives Functional groups derived fromcarboxylic acidare common in pharmaceuticals. Examples includeanhydrides, acylhalides, esters, amides,imides,lactams,lactones, andthiol esters. Esters (including lactones) and amides (including lactams) are among the most comm...
Regardless of the different bulk properties of the terphenyl carboxylates 26–29 and the thiadiazole derivatives 30, 31, the monolayer behavior is quite similar. The π/A-isotherms of the acid 30 and of the ethyl ester 31 indicate the formation of just a condensed monolayer film with the area...
