Reference Materials for qNMR

Reference materials (RMs) for qNMR are used as either internal or external standards for purposes of quantitation. RMs used as internal standards need to be highly pure, chemically inert, non-hygroscopic and non-volatile, give rise to simple spectra with non-overlapping resonances of the sample and be soluble in common deuterated NMR solvents.

Primary Certified Reference Materials for 1H qNMR

3,5-Bis(trifluoromethyl)benzoic acid (NMIJ CRM 4601-a)

Benzoic Acid (NIST PS1, Primary standard or qNMR)

Secondary Certified Reference Materials for qNMR

"TraceSure" product line of CRMs for qNMR, manufactured by Wako Pure Chemicals.

"TraceCERT" product line of CRMs for qNMR, manufactured by Sigma-Aldrich
