¹ HPLC analysis is carried out on an Agilent Poroshell column, with H₃PO₄ / NH₃ buffer system at pH=2.6 and UV-Vis detection
² Calculated purity = 100% - (Other cyclodextrin-related impurities + Sodium formate content + Residual solvents)

IMPORTANT: the compound is supplied in slightly acidic form for stability reasons; the actual molar sodium content (n) is indicated on the Certificate of Analysis of each batch.

Notes: the compound is a single isomer.
Comments: only for reagent and laboratory purposes, not for human use.
Storage: at -20 °C, under inert atmosphere, in tightly closed container.
