Chemical Structure
Description
The occurrence of Ethyl 2-(2-oxo-5-((prop-2-yn-1-yloxy)methyl)tetrahydrofuran-3-yl)acetate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Ethyl 2-(2-oxo-5-((prop-2-yn-1-yloxy)methyl)tetrahydrofuran-3-yl)acetate (CAS 69352-39-2), a certified reference material (molecular formula C12H16O5, MW 240.25 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, Ethyl 2-(2-oxo-5-((prop-2-yn-1-yloxy)methyl)tetrahydrofuran-3-yl)acetate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 240.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), Ethyl 2-(2-oxo-5-((prop-2-yn-1-yloxy)methyl)tetrahydrofuran-3-yl)acetate 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.
