Based on its molecular formula C25H39N7O3Si2, (5-(1-((2-(Trimethylsilyl)ethoxy)methyl)-3-(1-((2-(trimethylsilyl)ethoxy)methyl)-1H-imidazol-2-yl)-1H-indazol-6-yl)-2H-1,2,3-triazol-4-yl)methanol contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 541.79 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
(5-(1-((2-(Trimethylsilyl)ethoxy)methyl)-3-(1-((2-(trimethylsilyl)ethoxy)methyl)-1H-imidazol-2-yl)-1H-indazol-6-yl)-2H-1,2,3-triazol-4-yl)methanol (CAS 1956366-49-6) is a high-purity analytical reference standard with the molecular formula C25H39N7O3Si2 and a molecular weight of 541.79 g/mol.
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.
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.
