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 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
³ Calculated purity (w/w%) = ((100 (w/w%) - Sodium formate content (w/w%) - Residual solvents (w/w%))*Purity (area%))/100

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