Compared with other compounds in its class, the molecular weight of 152.21 g/mol gives 1-(3-Methylthiophen-2-yl)prop-2-yn-1-ol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1-(3-Methylthiophen-2-yl)prop-2-yn-1-ol (CAS 857971-86-9), a certified reference material (molecular formula C8H8OS, MW 152.21 g/mol) for analytical method development and quality control.
The molecular framework of 1-(3-Methylthiophen-2-yl)prop-2-yn-1-ol (C8H8OS) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional 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), 1-(3-Methylthiophen-2-yl)prop-2-yn-1-ol 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.
