Each unit of ERM-AE003 consists of approximately 100 mL of pure tetramethylurea under argon atmosphere in a leak-proof screw-cup amber glass bottle (with break ring) individually placed in a multilayer pouch. /// Identity confirmation and purity assessment of the material were carried out by GC-MS, 1H-NMR, 13C-NMR and GC-FID. The water content was determined by coulometric Karl Fischer titration (C-KFT). SNIF-NMR analyses for homogeneity, stability and characterisation were carried out strictly adhering to the method OIVMA-AS311-05.
