PubChem computed values are shown separately from the ChEBI record. An exact InChIKey match was used to connect the records. Molecular descriptors do not describe a supplied product’s purity, particle size or performance.

Molar masses differ between sources. Check isotope composition, source conventions and the original records before calculating a precise quantity.
