Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
Ethyl 1-amino-5-bromo-4-fluoro-2,3-dihydro-1H-indene-1-carboxylate (CAS 2089649-43-2), molecular formula C12H13BrFNO2 and molecular weight 302.14 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C12H13BrFNO2, Ethyl 1-amino-5-bromo-4-fluoro-2,3-dihydro-1H-indene-1-carboxylate contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 302.14 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.
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.
