Dimethyl 4-oxo-4H-pyran-2,6-dicarboxylate CAS 6558-96-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Dimethyl 4-oxo-4H-pyran-2,6-dicarboxylate.

CATO supplies Dimethyl 4-oxo-4H-pyran-2,6-dicarboxylate (CAS 6558-96-9), a certified reference material (molecular formula C9H8O6, MW 212.16 g/mol) for analytical method development and quality control.

The molecular framework of Dimethyl 4-oxo-4H-pyran-2,6-dicarboxylate (C9H8O6) 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
