Physicochemical Characteristics of Drug Substances

1. Physical Form (Crystal & Amorphous) Crystalline Form: Crystal Lattice Structure: Crystalline substances have a defined and repetitive arrangement of molecules. This structure is characterized by unit cells that repeat in three dimensions. Types of Crystals: Includes polymorphs (different crystal forms of the same compound), hydrates/solvates (crystals containing solvent molecules), and co-crystals (crystals composed of … Read more
