Chemical Structure
Description
As a certified reference material (CRM), 1-(5-Methylfuran-2-yl)but-3-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.
CATO supplies 1-(5-Methylfuran-2-yl)but-3-yn-1-ol (CAS 57544-94-2), a certified reference material (molecular formula C9H10O2, MW 150.17 g/mol) for analytical method development and quality control.
The molecular framework of 1-(5-Methylfuran-2-yl)but-3-yn-1-ol (C9H10O2) is characterized by a carboxylic acid group, 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.
