1185293-40-6 1-[5-Amino-1-(2-hydroxyethyl)-1H-benzimidazol-2-yl]ethan-1-ol--hydrogen chloride (1/2) DTXSID10673820 (CAS 1185293-40-6), molecular formula C11H15N3O2HCl and molecular weight 257.72 g/mol, is a CATO reference standard with documented purity and traceability.
1185293-40-6 1-[5-Amino-1-(2-hydroxyethyl)-1H-benzimidazol-2-yl]ethan-1-ol--hydrogen chloride (1/2) DTXSID10673820 (C11H15N3O2HCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
