MOLECULAR REFERENCE

The molecule behind every compound

Schematic structure figures paired with verified reference values - molecular formula, average mass, CAS number and amino-acid sequence - for every compound in the catalog. Figures illustrate connectivity, not measured conformation; exact identity for a given batch is confirmed by LC–MS on its certificate.

Structure figures are schematics generated for visual reference - they show approximate connectivity, not a measured conformation. Molecular formula and average mass are nominal values for the parent compound; verified identity for a given lot is confirmed by LC–MS on its Certificate of Analysis. Values shown as “See COA” are compound- or lot-specific.
