5720-26-3 5-(2-Aminoethyl)pyrogallol hydrochloride 1,2,3-Benzenetriol, 5-(2-aminoethyl)-, monohydrochloride EINECS 227-223-8 5-(2-Aminoethyl)-1,2,3-benzenetriol hydrochloride 5-(2-Aminoethyl)pyrogallol HCl (CAS 5720-26-3), molecular formula C8H17NO3HCl and molecular weight 211.69 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C8H17NO3HCl, 5720-26-3 5-(2-Aminoethyl)pyrogallol hydrochloride 1,2,3-Benzenetriol, 5-(2-aminoethyl)-, monohydrochloride EINECS 227-223-8 5-(2-Aminoethyl)-1,2,3-benzenetriol hydrochloride 5-(2-Aminoethyl)pyrogallol HCl contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 211.69 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
