And the article was included in Anales de la Real Academia de Farmacia in 1984.Recommanded Product: 5003-48-5 The following contents are mentioned in the article:
Acetylsalicylic acid [50-78-2], lysine acetylsalicylic acid [37933-78-1], and benorilate [5003-48-5] were determined by reversed-phase ion-pair HPLC in a variety of analgesic formulations containing codeine [76-57-3], phenacetin [62-44-2], caffeine [58-08-2], dextropropoxyphene [469-62-5], ascorbic acid [50-81-7], thiamine [59-43-8], pyridoxol [65-23-6], cyanocobalamine [68-19-9], phenylephrine [59-42-7], chlorpheniramine maleate [113-92-8], and lidocaine [137-58-6]. The stationary phase was LiChrosorb RP18 or RP8. In addition salicylic acid [69-72-7] was determined in the same formulations and results were compared to USP and British Pharmacopeia methods. The lower detection limit was 1 μg/mL. This study involved multiple reactions and reactants, such as 4-Acetamidophenyl 2-acetoxybenzoate (cas: 5003-48-5Recommanded Product: 5003-48-5).
4-Acetamidophenyl 2-acetoxybenzoate (cas: 5003-48-5) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.Recommanded Product: 5003-48-5
