Chemical Structure

Dibromonitro-acetic Acid Ethyl Ester CAS 100366-31-2 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 290.89 g/mol gives Dibromonitro-acetic Acid Ethyl Ester distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Dibromonitro-acetic Acid Ethyl Ester (CAS 100366-31-2), molecular formula C4H5Br2NO4 and molecular weight 290.89 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Dibromonitro-acetic Acid Ethyl Ester (C4H5Br2NO4) is characterized by a carbohydrate-derived structure, an amide group, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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), Dibromonitro-acetic Acid Ethyl Ester 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.
