Sodium acetate [127-09-3] M 82.0, m 324°, d 1.53. Crystd from acetic acid and pumped under vacuum for lOh at 120°. Alternatively, crystd from aqueous EtOH, as the trihydrate. This material can be converted to the anhydrous salt by heating slowly in a porcelain, nickel or iron dish, so that the salt liquefies. Steam is evolved and the mass again solidifies. Heating is now increased so that the salt melts again. (NB if it is heated too strongly, the salt chars.) After several minutes, the salt is allowed to solidify and cooled to a convenient temperature before being powdered and bottled (water content should now less than 0.02%).

The main use of TLC in analysis of amoxicillin and its formulated products is as an identity test. A major study [105] using silica gel and silanised silica gel plates with thirty five different mobile phases and iodine vapour detection produced a system, on silanised plates with ammonium acetate/acetone mobile phase, in which amoxicillin was separated from all the other penicillins studied. A slightly modified version of this system was subsequently introduced into the European and British Pharmacopoeia monographs for amoxicillin trihydrate and sodium salt [2]. The British [57,58] and US [9] Pharmacopoeias specify other TLC systems for identification of amoxicillin in formulated products. Simple TLC methods have been developed for identification of several compounds on the WHO essential drugs list, to help combat counterfeiting [106]. For amoxicillin, systems using ethyl acetate/acetic acid/water or acetone/toluene/acetic acid/water with silica gel plates were recommended.

However, at zero buffer concentration the maximum stability was shifted to a pH of 5.85. Ampicillin was stable in solutions at pH 3 - 9 when stored for 24 hours at 5°C and 25°C. Ampicillin was unstable in solutions at pH 10 when stored at above conditions. Bundgaard demonstrated a metastable intermediate in iso-meration of penicillin to penicillenic acid in aqueous solutions. The degradation of ampicillin trihydrate in solution is greatly influenced not only by pH, but also by the types of buffer salts used j. 2-Amino-2 (hydroxymethyl)-1,3-propanediol (Tris) buffer of pH 7 is highly deleterious to the stability of ampicillin, but not at pH 5.0. Citrate presents a converse pattern in that ampicillin is relatively stable at pH 7 but not so at pH 5. Phosphate is intermediate in action but tends to resemble the Tris pattern. Jacobson and Russo-Alesi prepared ampicillin trihydrate solutions at a concentration of 5 mg/ml by dissolving it in buffer solutions of pH 5.0 or pH 7.0 prepared from O.lM sodium acetate and acetic acid and in buffers of pH 8.0 or pH 8.8 prepared from O.lM 2-amino-2 (hydroxy methyl)- ,... 

A colourless crystalline compound, CHaCOONa, which is known as the anhydrous salt (r.d. 1.52 m.p. 324°C) or the trihydrate (r.d. 1.45 loses water at 58°C). Both forms are soluble in water and in ethoxyethane, and slightly soluble in ethanol. The compound maybe prepared by the reaction of ethanoic acid (acetic acid) with sodium carbonate or with sodium hydroxide. Because it is a salt of a strong base...
