Chemical Structure

N-Methyltetrachlorophthalimide CAS 14737-80-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 298.94 g/mol gives N-Methyltetrachlorophthalimide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

N-Methyltetrachlorophthalimide (CAS 14737-80-5) is a high-purity analytical reference standard with the molecular formula C9H3Cl4NO2 and a molecular weight of 298.94 g/mol.

The molecular framework of N-Methyltetrachlorophthalimide (C9H3Cl4NO2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine 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. 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.

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.
