Chemical Structure

Ethyl Benzoate CAS 93-89-0 chemical structure

Description

Ethyl Benzoate (CAS 93-89-0), molecular formula C9H10O2 and molecular weight 150.17 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Ethyl Benzoate (C9H10O2) 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 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 Benzoate 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.
