6-Methyl-2-oxo-2H-pyran-4-yl pivalate CAS 22131-82-4

Description

Compared with other compounds in its class, the molecular weight of 210.23 g/mol gives 6-Methyl-2-oxo-2H-pyran-4-yl pivalate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

6-Methyl-2-oxo-2H-pyran-4-yl pivalate (CAS 22131-82-4) is a high-purity analytical reference standard with the molecular formula C11H14O4 and a molecular weight of 210.23 g/mol.

The molecular framework of 6-Methyl-2-oxo-2H-pyran-4-yl pivalate (C11H14O4) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
