Reference Substances, Primary Standards

We provide compounds in high reference purity, suitable for the usage as primary standards (reference compounds). This quality is obtained in our labs by optimized preparative HPLC-MS separation followed by multiple crystallization steps. Purities up to 99.8% (HPLC) are possible on request. The compound can be obtained from your or from our material.

Special Services

  • Qualification of primary standards with comprehensive documentation (Certificate of Analysis, analytical results, NMR Reports, results, chromatograms, spectra).
  • Re-Anaylsis and Updating of Certificates of Analysis

Our standard Certificate of Analysis (CoA) for Primary Standards contains parameters like:

  • U(H)PLC-MS analytics
  • Extended NMR (like 1H, 13C, HSQC, HMBC, NOESY, COSY)
  • Quantitative NMR
  • Water content
  • Production date, analysis date
  • Appearance
  • Storage recommendation
  • Expiry Date

The format of the Certificate, the analytical methods and parameter are discussed and agreed in advance. Further methods can be provided on request.

All extra analytics and a certificate can also be requested for every of our products, as well as for external samples.
