Chemical Structure
Description
7-(TERT-BUTYL)-6-((1-ETHYL-1H-1,2,4-TRIAZOL-5-YL)METHOXY)-3-(2-FLUOROPHENYL)-[1,2,4]TRIAZOLO[4,3-B]PYRIDAZINE (CAS 252977-51-8), molecular formula C20H22FN7O and molecular weight 395.43 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 7-(TERT-BUTYL)-6-((1-ETHYL-1H-1,2,4-TRIAZOL-5-YL)METHOXY)-3-(2-FLUOROPHENYL)-[1,2,4]TRIAZOLO[4,3-B]PYRIDAZINE (C20H22FN7O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), 7-(TERT-BUTYL)-6-((1-ETHYL-1H-1,2,4-TRIAZOL-5-YL)METHOXY)-3-(2-FLUOROPHENYL)-[1,2,4]TRIAZOLO[4,3-B]PYRIDAZINE 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.
