Chemical Structure
Description
4-(2-Bromo-1-(2-methoxyphenyl)ethoxy)tetrahydro-2H-pyran (CAS 1455376-95-0), molecular formula C14H19BrO3 and molecular weight 315.20 g/mol, is a CATO reference standard with documented purity and traceability.
4-(2-Bromo-1-(2-methoxyphenyl)ethoxy)tetrahydro-2H-pyran (C14H19BrO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. 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 4-(2-Bromo-1-(2-methoxyphenyl)ethoxy)tetrahydro-2H-pyran 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.
