Description
CATO supplies 4-((Tetrahydro-2H-pyran-2-yl)oxy)but-2-yn-1-ol (CAS 64244-47-9), a certified reference material (molecular formula C9H14O3, MW 170.21 g/mol) for analytical method development and quality control.
Structurally, 4-((Tetrahydro-2H-pyran-2-yl)oxy)but-2-yn-1-ol (C9H14O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 170.21 g/mol, it falls into the medium-molecular-weight range. 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), 4-((Tetrahydro-2H-pyran-2-yl)oxy)but-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.
