Chemical Structure
Description
Phenylmethyl 5-methyl-2-oxo-1,3-dioxane-5-carboxylate (CAS 247142-68-3) is a high-purity analytical reference standard with the molecular formula C13H14O5 and a molecular weight of 250.25 g/mol.
The molecular framework of Phenylmethyl 5-methyl-2-oxo-1,3-dioxane-5-carboxylate (C13H14O5) 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.
As a certified reference material (CRM), Phenylmethyl 5-methyl-2-oxo-1,3-dioxane-5-carboxylate 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.
