5-((Pentylthio)methyl)isoxazol-3(2H)-one CAS 89660-68-4

Description

As a certified reference material (CRM), 5-((Pentylthio)methyl)isoxazol-3(2H)-one 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.

CATO supplies 5-((Pentylthio)methyl)isoxazol-3(2H)-one (CAS 89660-68-4), a certified reference material (molecular formula C9H15NO2S, MW 201.29 g/mol) for analytical method development and quality control.

Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 5-((Pentylthio)methyl)isoxazol-3(2H)-one is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 201.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
