Chemical Structure
Description
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 supplies 1-(4-Chlorophenyl)heptan-2-yl 2-(oxazol-4-yl)acetate (CAS 89006-89-3), a certified reference material (molecular formula C18H22ClNO3, MW 335.83 g/mol) for analytical method development and quality control.
1-(4-Chlorophenyl)heptan-2-yl 2-(oxazol-4-yl)acetate (C18H22ClNO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
CATO manufactures 1-(4-Chlorophenyl)heptan-2-yl 2-(oxazol-4-yl)acetate 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.
