1-[(3,5-dimethylisoxazol-4-yl)sulfonyl]piperidine-4-carboxylic acid CAS 697258-72-3 chemical structure

Description

The occurrence of 1-[(3,5-dimethylisoxazol-4-yl)sulfonyl]piperidine-4-carboxylic acid is closely related to a nitrogen-containing heterocyclic scaffold, 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.

1-[(3,5-dimethylisoxazol-4-yl)sulfonyl]piperidine-4-carboxylic acid (CAS 697258-72-3) is a high-purity analytical reference standard with the molecular formula C11H16N2O5S and a molecular weight of 288.32 g/mol.

Based on its molecular formula C11H16N2O5S, 1-[(3,5-dimethylisoxazol-4-yl)sulfonyl]piperidine-4-carboxylic acid contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 288.32 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), 1-[(3,5-dimethylisoxazol-4-yl)sulfonyl]piperidine-4-carboxylic acid 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.
