Chemical Structure
Description
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
6-Bromo-3-(2-((2-((tert-butyldimethylsilyl)oxy)ethyl)thio)phenyl)-[1,2,4]triazolo[4,3-a]pyridine (CAS 1344738-13-1) is a high-purity analytical reference standard with the molecular formula C20H26BrN3OSSi and a molecular weight of 464.49 g/mol.
6-Bromo-3-(2-((2-((tert-butyldimethylsilyl)oxy)ethyl)thio)phenyl)-[1,2,4]triazolo[4,3-a]pyridine (C20H26BrN3OSSi) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
