Chemical Structure
Description
As a certified reference material (CRM), 2-(2-Ethyl-1H-benzo[d]imidazol-1-yl)butanoic acid hydrochloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
2-(2-Ethyl-1H-benzo[d]imidazol-1-yl)butanoic acid hydrochloride (CAS 1609396-01-1), molecular formula C13H16N2O2HCl and molecular weight 268.74 g/mol, is a CATO reference standard with documented purity and traceability.
2-(2-Ethyl-1H-benzo[d]imidazol-1-yl)butanoic acid hydrochloride (C13H16N2O2HCl) 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, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
