Study of the chemical and physical properties of the drug components

Physicochemical Characterization

APIs & Excipients per ICH Q6A Preformulation

Overview Service

Capzer Pharmaceuticals determines chemical identity, solid-state properties, and solution behavior for APIs like Empagliflozin (C23H27ClO7, 450.91 g/mol) and Gabapentin plus excipients. Our FDA/DEA-registered cGMP laboratory uses HPLC, DSC, XRPD, and Karl Fischer to generate data supporting formulation design and ANDA specifications.

Chemical Properties Assessed

Complete monograph compliance verifies structure and purity.

  • Molecular formula/weight, CAS number, elemental analysis.

  • pKa, logP (1.7 for Empagliflozin), partition coefficient.

  • Solubility profiles: pH 1.2–8.0, cosolvents, biorelevant media.

Physical Properties Profile

Solid-state and bulk characteristics guide processing.

  • Particle size/shape (laser diffraction, SEM), polymorphism (XRPD, DSC).

  • Hygroscopicity (DVS), flowability (Carr’s index), bulk/tapped density.

  • Thermal: Melting point, glass transition, decomposition onset.​

Key Capabilities

Benefits for Partners

Partners receive comprehensive profiles for Empagliflozin tablet prototypes from our ISO 17025 facility, enabling robust QbD formulation and 24-month stability predictions.
