4-Bromo-2-(5-(thiophen-2-yl)-4,5-dihydro-1H-pyrazol-3-yl)phenol (CAS 610277-76-4) is a high-purity analytical reference standard with the molecular formula C13H11BrN2OS and a molecular weight of 323.21 g/mol.
The molecular framework of 4-Bromo-2-(5-(thiophen-2-yl)-4,5-dihydro-1H-pyrazol-3-yl)phenol (C13H11BrN2OS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures 4-Bromo-2-(5-(thiophen-2-yl)-4,5-dihydro-1H-pyrazol-3-yl)phenol under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
