Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 769172-81-8 (1S)-6,7-Dimethoxy-1-{2-[4-(trifluoromethyl)phenyl]ethyl}-1,2,3,4-tetrahydroisoquinoline DTXSID00657513.
CATO supplies 769172-81-8 (1S)-6,7-Dimethoxy-1-{2-[4-(trifluoromethyl)phenyl]ethyl}-1,2,3,4-tetrahydroisoquinoline DTXSID00657513 (CAS 769172-81-8), a certified reference material (molecular formula C20H22F3NO2, MW 365.39 g/mol) for analytical method development and quality control.
Based on its molecular formula C20H22F3NO2, 769172-81-8 (1S)-6,7-Dimethoxy-1-{2-[4-(trifluoromethyl)phenyl]ethyl}-1,2,3,4-tetrahydroisoquinoline DTXSID00657513 contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 365.39 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.
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.
