The Nuclear Magnetic Resonance Core supports MSK researchers by providing essential analytical services, access and education for analytical instrumentation and related shared scientific resources. Our main instrumentation includes high field nuclear magnetic resonance, mass spectrometry and optical spectroscopic instruments. Our primary focus concerns small molecule synthetic organic chemistry/drug development; however we support and welcome all MSK research that is within our capabilities. Through the use of our instruments, the facility affords investigators the ability to monitor chemical reactions, analysis for determination of molecular structure, chemical mechanisms, purity, stability, biological uptake and other properties of chemical compounds.
