43134-09-4 1-(4-Dimethylamino-phenyl)-3-(4-dimethylimmonium-cyclohexa- 2,5-dien-1-ylidene)-2-oxo-cyclobuten-4-olate MFCD00142504 CAS 43134-09-4

Description

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.

43134-09-4 1-(4-Dimethylamino-phenyl)-3-(4-dimethylimmonium-cyclohexa- 2,5-dien-1-ylidene)-2-oxo-cyclobuten-4-olate MFCD00142504 (CAS 43134-09-4), molecular formula C20H26N2O2 and molecular weight 326.43 g/mol, is a CATO reference standard with documented purity and traceability.

43134-09-4 1-(4-Dimethylamino-phenyl)-3-(4-dimethylimmonium-cyclohexa- 2,5-dien-1-ylidene)-2-oxo-cyclobuten-4-olate MFCD00142504 (C20H26N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
