Ethyl 3-oxo-5-tosylpentanoate CAS 1093348-62-9

Description

Compared with other compounds in its class, the molecular weight of 298.35 g/mol gives Ethyl 3-oxo-5-tosylpentanoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Ethyl 3-oxo-5-tosylpentanoate (CAS 1093348-62-9), molecular formula C14H18O5S and molecular weight 298.35 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Ethyl 3-oxo-5-tosylpentanoate (C14H18O5S) is characterized by a sulfone group, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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 3-oxo-5-tosylpentanoate 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.
