(αR,βR,2S)-β-Methoxy-α-methyl-N-[(1S)-2-phenyl-1-(2-thiazolyl)ethyl]-2-pyrrolidinepropanamide CAS 133120-91-9

Description

As a certified reference material (CRM), (αR,βR,2S)-β-Methoxy-α-methyl-N-[(1S)-2-phenyl-1-(2-thiazolyl)ethyl]-2-pyrrolidinepropanamide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

(αR,βR,2S)-β-Methoxy-α-methyl-N-[(1S)-2-phenyl-1-(2-thiazolyl)ethyl]-2-pyrrolidinepropanamide (CAS 133120-91-9), molecular formula C20H27N3O2S and molecular weight 373.51 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (αR,βR,2S)-β-Methoxy-α-methyl-N-[(1S)-2-phenyl-1-(2-thiazolyl)ethyl]-2-pyrrolidinepropanamide (C20H27N3O2S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
