'has role' some 'NMR chemical shift reference compound' axiom is missing from the CHEBI.owl for some compounds at the moment and we need to wait for the new CHEBI owl version. Here is a list of things to review after refreshing:

• tetramethylsilane-d12 CHEBI:231529 has role NMR chemical shift reference compound
• potassium hexachloroniobate(1−) CHEBI:231541 has role NMR chemical shift reference compound
• magnesium dichloride CHEBI:6636 is under grouping class 25Mg spectrum chemical shift reference compound
• Dinitrooxyalumanyl nitrate CHEBI:231496 is under grouping class 27Al spectrum chemical shift reference
• ammonium sulfate CHEBI:62946 is under grouping class 33S spectrum chemical shift reference
• Vanadium oxytrichloride CHEBI:231500 is under grouping class 50V spectrum chemical shift reference
• Vanadium oxytrichloride CHEBI:231500 is under grouping class 51V spectrum chemical shift reference
• Potassium Permanganate CHEBI:231501 is under grouping class 55Mn spectrum chemical shift reference
