Nuclear magnetic resonance (NMR)


  • NMR spectroscopy (400-800 MHz) to study samples in solution and observe active nuclei (1H, 13C, 19F, 31P, 113Cd, 195Pt, 29Si, 15N, etc.).

Range of services

  • Structural determination of organic and inorganic compounds (small-medium molecular weight).
  • One- and two-dimensional experiments (COSY, DQF, COSY, TOCSY, HSQC, HMBC, NOESY). Difussion experiments DOSY.
  • Combined experiments such as HMQC-TOCSY and other heteronuclear experiments.
  • Analysis of complex structures (natural products, compounds of biological interest) Multi-dimensional experiments for structural determination in proteins.
  • Combined use of 1H, 13C and 15N for the study of complex molecules such as proteins through 2 and 3D inverse detection experiments.
  • Implementation of new sequences and methods; methodological development and application.
  • Control of synthesis processes and/or purification of organic compounds Determination of impurities and minority components; quantitative analyses.
  • Process monitoring, kinetic monitoring; variable temperature experiments.
  • Determination of interactions between proteins and low-molecular weight compounds.
  • Work conducted in accordance with standardized procedures (SOP) for the analysis of APIs (USP, European Pharmacopoeia and ASTM standards). DOSY diffusion experiments.
  • Identification of compounds, spectral assignment, reports and evaluations.

Examples of application

  • NMR spectral assignment for the identification of structures.
  • Heparin analysis (in compliance with FDA-USP and European and Japanese Pharmacopoeia standards).
  • Poloxamer analysis (according to EP, USP procedure).
  • PGLA polymer analysis (in accordance with ASTM standards).
  • Identification analysis for compliance with REACH standard.
  • Study of metabolites resulting from the application of an active ingredient (whether directly or through a prior HPLC system treatment).
  • Quantitative analysis through the use of internal patterns.
  • Determination of the degree of deuteration.
  • Application of NMR in the analysis of food products (oils, dairy, juices, additives, etc.).
  • Consulting and training for the optimization of the use of existing NMR instrumentation at private centers.
