2-(4-Iodo-5-(3-methoxyphenyl)-1H-pyrazol-1-yl)ethanol (CAS 1708037-72-2), molecular formula C12H13IN2O2 and molecular weight 344.15 g/mol, is a CATO reference standard with documented purity and traceability.
2-(4-Iodo-5-(3-methoxyphenyl)-1H-pyrazol-1-yl)ethanol (C12H13IN2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, iodine 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. 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.
CATO manufactures 2-(4-Iodo-5-(3-methoxyphenyl)-1H-pyrazol-1-yl)ethanol 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.
