Melting pointOrganic compoundParticle sizePharmaceutical preformulationThree bulk organic compounds of pharmaceutical interest, namely salicylic acid, benzophenone, and acetaminophen, have been analyzed by differential scanning calorimetry as a function of their particle size. For that purpose, the raw powders...
The present invention relates to a process for the modification of the physical properties (viscosity, melting point, etc.), of colloidal substances and more specially to a process for the modification of the physical properties of organic isocolloids. By "isocolloids" 'or "isocolloidal substances...
The term "primer" refers to an oligonucleotide, whether naturally occurring or synthetically produced, which is capable of acting as a point of initiation of synthesis when placed under conditions in which synthesis of a primer extension product complementary to a nucleic acid strand (that is, temp...
