2-Ethoxy-5-(1-tosylpyrrolidin-2-yl)pyridine CAS 1352509-32-0

Description

The occurrence of 2-Ethoxy-5-(1-tosylpyrrolidin-2-yl)pyridine is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-Ethoxy-5-(1-tosylpyrrolidin-2-yl)pyridine (CAS 1352509-32-0), molecular formula C18H22N2O3S and molecular weight 346.44 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-Ethoxy-5-(1-tosylpyrrolidin-2-yl)pyridine (C18H22N2O3S) 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.

As a certified reference material (CRM), 2-Ethoxy-5-(1-tosylpyrrolidin-2-yl)pyridine 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.
