Chemical Structure
Description
2-((4'-Methyl-[1,1'-biphenyl]-4-yl)oxy)-1-morpholinoethan-1-one (CAS 303031-97-2), molecular formula C19H21NO3 and molecular weight 311.37 g/mol, is a CATO reference standard with documented purity and traceability.
2-((4'-Methyl-[1,1'-biphenyl]-4-yl)oxy)-1-morpholinoethan-1-one (C19H21NO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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'-Methyl-[1,1'-biphenyl]-4-yl)oxy)-1-morpholinoethan-1-one 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.
