Chemical Structure

Ethyl 2-(3-bromo-4-cyano-2-nitrophenyl)acetate CAS 1806062-34-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 2-(3-bromo-4-cyano-2-nitrophenyl)acetate.

Ethyl 2-(3-bromo-4-cyano-2-nitrophenyl)acetate (CAS 1806062-34-9), molecular formula C11H9BrN2O4 and molecular weight 313.10 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Ethyl 2-(3-bromo-4-cyano-2-nitrophenyl)acetate (C11H9BrN2O4) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
