Absolute Structure Determination and Crystal Identification

Single-crystal growth and structure determination are the gold-standard methods for confirming the absolute configuration of drug molecules and identifying crystal forms. Following successful crystallization, advanced techniques such as Single Crystal X-ray Diffraction (SCXRD) and Microcrystal Electron Diffraction (MicroED) are applied to generate high-resolution structural data and define molecular architecture.

High Success Rate in Single-Crystal Growth and Structure Determination

Growing high-quality single crystals remains a key challenge in structure determination. While industry success rates for single-crystal growth are typically limited, specialized methodologies and crystallization strategies enable success rates exceeding 90%. Extensive experience across diverse compound classes supports reliable structure determination for complex drug molecules.

>90% Success Rate

Advanced Instrumentation and Tiered Analytical Capabilities

A tiered analytical approach enables structure determination across a wide range of crystal sizes and complexities:

Single-crystal X-ray diffraction (SCXRD)

Two advanced diffractometers support structure determination for the majority of crystalline samples.

Synchrotron-based X-ray diffraction

For challenging samples (<1–20 µm), access to the National Synchrotron Light Source II (Brookhaven National Laboratory) enables high-resolution data collection.

Microcrystal Electron Diffraction (MicroED)

Applied to micro- and nanocrystals (typically < 1 µm) for structure determination when conventional X-ray methods are not feasible.

Single Crystal X-ray Diffraction (SCXRD)

Rapid structure determination: Data collection and analysis can be completed within minutes for suitable samples.
High sensitivity: Capable of resolving crystal structures from samples as small as ~10 µm.
Proven reliability: Extensive experience in structure determination across a wide range of pharmaceutical compounds.

Microcrystal Electron Diffraction (MicroED)

Suitable for microcrystalline and nanocrystalline samples (<200 nm): Enables structure determination when crystals are too small for conventional X-ray diffraction.
High signal-to-noise ratio and spatial resolution: Provides high-quality diffraction data from extremely small crystals.
Simultaneous diffraction and imaging capability: Combines structural analysis with real-time imaging to support accurate structure determination.
