Chemical Structure

4-Acetoxy­butyric anhydride CAS 150620-32-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 274.27 g/mol gives 4-Acetoxy­butyric anhydride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-Acetoxy­butyric anhydride (CAS 150620-32-9), molecular formula C12H18O7 and molecular weight 274.27 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-Acetoxy­butyric anhydride (C12H18O7) 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.

CATO manufactures 4-Acetoxy­butyric anhydride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
