1-(1-(3-Chloro-4-methylphenyl)-1H-1,2,3-triazol-4-yl)-2-(2,4-dichlorophenoxy)propan-1-one CAS 477847-89-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(1-(3-Chloro-4-methylphenyl)-1H-1,2,3-triazol-4-yl)-2-(2,4-dichlorophenoxy)propan-1-one.

1-(1-(3-Chloro-4-methylphenyl)-1H-1,2,3-triazol-4-yl)-2-(2,4-dichlorophenoxy)propan-1-one (CAS 477847-89-5), molecular formula C18H14Cl3N3O2 and molecular weight 410.68 g/mol, is a CATO reference standard with documented purity and traceability.

1-(1-(3-Chloro-4-methylphenyl)-1H-1,2,3-triazol-4-yl)-2-(2,4-dichlorophenoxy)propan-1-one (C18H14Cl3N3O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
