CATO supplies 836-42-0 A840619 [1-amino-2-(1H-indol-3-yl)ethyl]phosphonic acid [1-azanyl-2-(1H-indol-3-yl)ethyl]phosphonic acid (CAS 836-42-0), a certified reference material (molecular formula C14H25ClO, MW 244.80 g/mol) for analytical method development and quality control.
836-42-0 A840619 [1-amino-2-(1H-indol-3-yl)ethyl]phosphonic acid [1-azanyl-2-(1H-indol-3-yl)ethyl]phosphonic acid (C14H25ClO) contains a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
