“…The AEM buffer consists of 10 mM acetic acid, 10 mM ethylenediamine, and 30 mM mesylic acid, which is used to adjust the starting pH to about 1.7. The buffer capacity is nearly as uniformly distributed as in the case of the Britton-Robinson buffer, but a lower level is chosen (average of 4.4 mM/pH over pH [3][4][5][6][7][8][9][10][11]. This buffer capacity would allow the commercial pK a analyzers to easily set pH in increments of 0.2 across the pH range, using 0.5 M titrants.…”

“…Several excellent books and reviews serve as background material for the commentary covering the solubility of druglike molecules: general coverage of solubility [7][8][9][10]; salt formation/selection [11][12][13][14][15][16]; polymorphism [17][18][19][20]; analysis of saturated solution speciation [21][22][23][24][25][26][27]; dissolution/solubility of cocrystals [28][29][30][31][32][33][34][35][36][37]; anhydrous forms versus hydrates [16,38,39].…”

“…[8][9][10][11][12][13] Alguns artigos descrevem a utilização prática da análise térmica para cada aplicação prevista. Giordano et al relataram que o uso da temperatura de fusão do diclofenaco de sódio como parâmetro de pureza, como estabelecido pelas farmacopeias não é adequado, visto que seu processo de decomposição é complexo.…”

“…When polymorphism occurs, the molecules arrange themselves in two or more different ways in the crystal; either they may be packed differently in the crystal lattice or there may be differences in the orientation or conformation of the molecules at the lattice sites. [12,17] In general, polymorphs of a given compound have different physicochemical properties, such as melting point, solubility and density, so that the occurrence of polymorphism has important formulation, biopharmaceutical, and chemical process implications. In addition to polymorphs, solvates (inclusion of the solvent of crystallization), hydrates (inclusion of water of crystallization), and amorphous forms (where no long-range order exists) may also exist [18] (e.g., polymorphism shown by estrone).…”
