Chemical Structure
Description
The occurrence of 2-Methoxy-1-(2-((3-methoxy-4-(4-methyl-1H-imidazol-1-yl)phenyl)amino)-6,7-dihydrothiazolo[5,4-c]pyridin-5(4H)-yl)ethanone is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Methoxy-1-(2-((3-methoxy-4-(4-methyl-1H-imidazol-1-yl)phenyl)amino)-6,7-dihydrothiazolo[5,4-c]pyridin-5(4H)-yl)ethanone (CAS 1077629-26-5), molecular formula C20H23N5O3S and molecular weight 413.49 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Methoxy-1-(2-((3-methoxy-4-(4-methyl-1H-imidazol-1-yl)phenyl)amino)-6,7-dihydrothiazolo[5,4-c]pyridin-5(4H)-yl)ethanone (C20H23N5O3S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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. 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.
As a certified reference material (CRM), 2-Methoxy-1-(2-((3-methoxy-4-(4-methyl-1H-imidazol-1-yl)phenyl)amino)-6,7-dihydrothiazolo[5,4-c]pyridin-5(4H)-yl)ethanone 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.
