3-(4-Chlorobenzoyl)-4-(2-fluorophenyl)-1-methylpyrrolidine CAS 338777-14-3

Description

3-(4-Chlorobenzoyl)-4-(2-fluorophenyl)-1-methylpyrrolidine (CAS 338777-14-3), molecular formula C18H17ClFNO and molecular weight 317.79 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 3-(4-Chlorobenzoyl)-4-(2-fluorophenyl)-1-methylpyrrolidine (C18H17ClFNO) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 317.79 g/mol, it falls into the moderately-high-molecular-weight range. 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.
