N-Benzylidene-3-(thiophen-2-yl)isoxazol-5-amine CAS 37853-21-7

Description

Compared with other compounds in its class, the molecular weight of 254.31 g/mol gives N-Benzylidene-3-(thiophen-2-yl)isoxazol-5-amine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

N-Benzylidene-3-(thiophen-2-yl)isoxazol-5-amine (CAS 37853-21-7), molecular formula C14H10N2OS and molecular weight 254.31 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of N-Benzylidene-3-(thiophen-2-yl)isoxazol-5-amine (C14H10N2OS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), N-Benzylidene-3-(thiophen-2-yl)isoxazol-5-amine 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.
