Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 5-(2-aminothiazol-4-yl)-2-((3-fluorobenzyl)oxy)benzoate.
Ethyl 5-(2-aminothiazol-4-yl)-2-((3-fluorobenzyl)oxy)benzoate (CAS 1416342-87-4), molecular formula C19H17FN2O3S and molecular weight 372.41 g/mol, is a CATO reference standard with documented purity and traceability.
Ethyl 5-(2-aminothiazol-4-yl)-2-((3-fluorobenzyl)oxy)benzoate (C19H17FN2O3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.
As a certified reference material (CRM), Ethyl 5-(2-aminothiazol-4-yl)-2-((3-fluorobenzyl)oxy)benzoate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
