Chemical Structure

1-Chloro-2-(chloromethyl)-3-nitrobenzene CAS 15258-72-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 206.03 g/mol gives 1-Chloro-2-(chloromethyl)-3-nitrobenzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1-Chloro-2-(chloromethyl)-3-nitrobenzene (CAS 15258-72-7) is a high-purity analytical reference standard with the molecular formula C7H5Cl2NO2 and a molecular weight of 206.03 g/mol.

Structurally, 1-Chloro-2-(chloromethyl)-3-nitrobenzene (C7H5Cl2NO2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 206.03 g/mol, it falls into the medium-molecular-weight range. 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.

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.
