Monitor API Physical Form in Stability to Detect Polymorph and Amorphous Shifts
Understanding the Tip: Why monitoring API solid state is essential: APIs may exist in multiple physical forms such as crystalline polymorphs, solvates, hydrates, or amorphous states—each with unique solubility, bioavailability, and stability characteristics. During storage, environmental stress like heat and humidity can trigger transitions from one form to another, affecting dissolution rate, absorption, and even…
