Description

Compared with other compounds in its class, the molecular weight of 327.85 g/mol gives Methyl (2S,4S)-4-[2-(tert-butyl)-4-methylphenoxy]-2-pyrrolidinecarboxylate hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Methyl (2S,4S)-4-[2-(tert-butyl)-4-methylphenoxy]-2-pyrrolidinecarboxylate hydrochloride (CAS 1354487-91-4), molecular formula C17H25NO3HCl and molecular weight 327.85 g/mol, is a CATO reference standard with documented purity and traceability.

Methyl (2S,4S)-4-[2-(tert-butyl)-4-methylphenoxy]-2-pyrrolidinecarboxylate hydrochloride (C17H25NO3HCl) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, 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 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.
