Identification 3 / IR (EP 2.2.24) conforms to theoretical structure
Purity / HPLC1   (EP 2.2.29) >90.0 area%
Other cyclodextrin-related impurities / HPLC1 (EP 2.2.29) <10.0 area%
Sodium formate content / CE (EP 2.2.47) <3.0 area%
Sodium content CE2 (EP 2.2.47) <10.0 w/w%
Residual solvents / TGM-MS (EP 2.2.34, 2.2.43) <10.0 w/w%
Purity calculated3 to be reported
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.
