1-[(2,4-dichlorophenyl)methyl]-3-[4-methyl-5-(prop-2-yn-1-ylsulfanyl)-4H-1,2,4-triazol-3-yl]-1,2-dihydropyridin-2-one 11E-368S 477853-20-6 CAS 477853-20-6

Description

1-[(2,4-dichlorophenyl)methyl]-3-[4-methyl-5-(prop-2-yn-1-ylsulfanyl)-4H-1,2,4-triazol-3-yl]-1,2-dihydropyridin-2-one 11E-368S 477853-20-6 (C18H14Cl2N4OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

1-[(2,4-dichlorophenyl)methyl]-3-[4-methyl-5-(prop-2-yn-1-ylsulfanyl)-4H-1,2,4-triazol-3-yl]-1,2-dihydropyridin-2-one 11E-368S 477853-20-6 (CAS 477853-20-6) is a high-purity analytical reference standard with the molecular formula C18H14Cl2N4OS and a molecular weight of 405.30 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.
