(S)-3-Ethyl-5-(pyrrolidin-2-yl)isoxazole CAS 147402-55-9

Description

The occurrence of (S)-3-Ethyl-5-(pyrrolidin-2-yl)isoxazole is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(S)-3-Ethyl-5-(pyrrolidin-2-yl)isoxazole (CAS 147402-55-9) is a high-purity analytical reference standard with the molecular formula C9H14N2O and a molecular weight of 166.22 g/mol.

The molecular framework of (S)-3-Ethyl-5-(pyrrolidin-2-yl)isoxazole (C9H14N2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide 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 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.

As a certified reference material (CRM), (S)-3-Ethyl-5-(pyrrolidin-2-yl)isoxazole 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.
