5-Chloro-2-[[3-methoxy-4-(4-methyl-1H-imidazol-1-yl)phenyl]methylene]pentanoic acid CAS 1225232-41-6

Description

5-Chloro-2-[[3-methoxy-4-(4-methyl-1H-imidazol-1-yl)phenyl]methylene]pentanoic acid (C17H19ClN2O3) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

5-Chloro-2-[[3-methoxy-4-(4-methyl-1H-imidazol-1-yl)phenyl]methylene]pentanoic acid (CAS 1225232-41-6) is a high-purity analytical reference standard with the molecular formula C17H19ClN2O3 and a molecular weight of 334.80 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.
