Drug Structure Confirmation Service
Drug structure confirmation is a fundamental step in pharmaceutical development, ensuring that the chemical identity of an active pharmaceutical ingredient (API) or drug product is consistent with its intended design. The precise determination of molecular structure underpins the reliability of drug safety, efficacy, and quality. Any deviation in molecular identity, stereochemistry, or structural integrity can lead to altered biological activity, reduced therapeutic effectiveness, or potential safety risks. As modern pharmaceuticals often involve complex molecules, from small-molecule drugs to advanced formulations, reliable structural confirmation is essential to guide discovery, support development, and enable successful commercialization.
Service at MtoZ Biolabs
MtoZ Biolabs provides a comprehensive Drug Structure Confirmation Service that integrates advanced analytical methods to characterize atomic connectivity, stereochemistry, and molecular conformation. This service not only helps in preventing misidentified or mischaracterized compounds but also supports batch-to-batch consistency, stability testing, and overall quality assurance.
Advanced Technology Platform for Drug Structure Confirmation:
🔸Mass Spectrometry (MS)
High-resolution LC-MS and GC-MS allow precise determination of molecular weight, isotopic distribution, and fragmentation pathways, confirming molecular formula and identifying potential impurities or isomers.
🔸Ultraviolet (UV) and Infrared (IR) Spectroscopy
UV spectroscopy helps characterize conjugated systems and chromophores, while IR spectroscopy provides chemical bonds and functional group verification, ensuring accurate structural assignments.
🔸Nuclear Magnetic Resonance (NMR) Spectroscopy
One-dimensional and two-dimensional NMR experiments deliver atomic-level connectivity, stereochemical information, and conformational insights, serving as a cornerstone of structure elucidation.
🔸X-ray Single Crystal Diffraction (XRSD)
When crystalline samples are available, XRSD offers direct visualization of three-dimensional molecular structures and absolute stereochemistry with unmatched accuracy.
🔸Circular Dichroism (CD) Spectroscopy
CD analysis enables secondary structure and chiral property assessment, supporting structural confirmation of chiral drugs and conformationally sensitive molecules.
Analysis Workflow
1. Sample Preparation and Verification
Initial inspection of submitted samples to confirm suitability for structural analysis. Specific preparation steps may be required to ensure compatibility with each analytical platform.
2. Instrumental Analysis
Use of complementary analytical platforms, such as MS, NMR, IR, UV, XRSD, and CD, to generate comprehensive structural information.
3. Data Integration
Correlation and cross-validation of data from different methods to ensure accuracy and eliminate ambiguity.
4. Structural Confirmation
Compilation of results into a unified interpretation to confirm molecular identity, stereochemistry, and overall structure.
5. Reporting
Preparation of a clear, regulatory-ready report summarizing experimental approaches, results, and expert interpretation.
