practically insoluble in chloroform and in ether It is soluble in acids and in alkalis.Storage Store in Dghtly-ctosed containers STANDARDSAminocaproic

less than 98 5 per cent and not more than 101 0 per cent of C6 H13 NO2 calculated with reference to the dried substance identification A. The infra-red absorption spectrum. Appendix 5.4. is concordant with the reference spectrum of aminocaproic acti or with the spectrum obtained from aminocaproic acid RS.B Carry out the method for thin-layer chromatagraphy. Appendix A 6, using silica gel G as the coating substance and a mixture of 25 volumes of ethanol (95%), 3 volumes, of water and 4 volumes of strong ammonia solution as the mobile phase Apply separately to the plate 2 ul of each of two solutions in water containing (1) 0 25% w/v of the substance being examined and {1} 0 25% w/v of ammocaproic acid RS After removal of the plate, spray it with a 0.25% w/v solution of ninhyonn in a mixture of equal volumes of methanol and pyndine and heat at I05a for 2 minutes. The principal spot in The chromatogram obtained with solution (1) corresponds to that in the chromatogram obtained with solution (2).C. Melts at about 204* with decomposition. Appendix 0 8 pH Between 7 5 and G 0. determined in a 20 D% wtv solution.. Appendix 9 ll.Clanty and colour of solution A 20 0% w/v solution remains clear for 24 hours. Appendix G 1. and is colourless, Appendix 6 2 Stability Place 30 0 g evenly spread in a shallow dish about 9 cm in diameter, cover and allow to stand at 100* ±20 for 72 hours. Dissolves sufficient water to produce 100.0 ml Prepare a 200% wfa solution of Trie substance being examined but without the above treatment.
