Chemical Structure
Description
[1-Methyl-2-[(tetrahydro-2H-pyran-2-yl)oxy]ethylidene]-propanedioic Acid Diethyl Ester (CAS 86958-53-4), molecular formula C15H24O6 and molecular weight 300.35 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C15H24O6, [1-Methyl-2-[(tetrahydro-2H-pyran-2-yl)oxy]ethylidene]-propanedioic Acid Diethyl Ester contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 300.35 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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-Methyl-2-[(tetrahydro-2H-pyran-2-yl)oxy]ethylidene]-propanedioic Acid Diethyl Ester 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.
