Chemical Structure
Description
2-(2-Bromophenyl)-2,6-dihydro-4H-thieno[3,4-c]pyrazol-3-amine (C11H10BrN3S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, bromine 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.
2-(2-Bromophenyl)-2,6-dihydro-4H-thieno[3,4-c]pyrazol-3-amine (CAS 1418273-33-2) is a high-purity analytical reference standard with the molecular formula C11H10BrN3S and a molecular weight of 296.19 g/mol.
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.
