Locality, Strength, and Hierarchy of Intermolecular Interactions in Crystallization
Self-assembling of molecules in crystallization is collectively driven by intermolecular interactions among the solute and solvent. Better understanding of nucleation mechanism may be perceived in light of the locality, strength, and hierarchy of intermolecular interactions.

Rational selection of solvents plays a critical role in solid form screening and production. On the one hand, a variety of solvents with different properties are chosen in form screening to maximize the screening space of searching for all potential solid forms because some solvents selectively favor the generation of a particular form as a result of crystallization kinetics.

In solution phase crystallisation processes, understanding and controlling the transition pathway associated with the assembly of molecules from their solvated state, into three-dimensional, ordered crystalline-solids, represents a significant grand challenge for the physical-chemical sciences. Crystallisation can be sub-divided into three-dimensional nucleation and two-dimensional, surface-mediated, crystal growth stages.
Read MoreFacilitating DS/DP development through integrated solid-state and crystallization development
Crystallization is an important and economic unit operation for the purification of pharmaceutical API. It also serves as the key step to define the required quality attribute of the API (e.g. solid form, particle size distribution) that would impact the subsequent processing (e.g. filtration, drying, milling) and drug product performance (e.g. dissolution, content uniformity). To successfully bring a compound into the market, an integrated approach to link the development of API solid form, isolation and dosage form is essential to ensure the robust delivery of the desired drug product quality, throughout the scale.
Read MoreA Challenging Path to Controlled Nano-API Crystallization and Isolation
Controlled crystallization of an API in submicron size was enabled based on an accurate solubility profile and a growth inhibition property via semi-continuous processing, to meet special formulation requirements. This process was also challenged by isolation of nano-API crystals to meet the low specification of residual salt content.
Read MoreParticle Surface Engineering for Predictive Enhancement of API Properties
Particle surface engineering is a cost-effective, promising route to achieve enhancements in the flowability, bulk density and other properties of a variety of cohesive active pharmaceutical ingredients (APIs). This presentation will discuss predictive enhancements after dry coating based particle surface engineering and discuss models and guidelines for the selection of flow aid type and amount, as well as predicting powder bulk properties from their particle-scale properties such as the particle size and distribution, materials density, surface energy, and surface roughness.
