Chemical Structure

2-Bromo-3,6-dichlorobenzaldehyde CAS 1114809-26-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 253.91 g/mol gives 2-Bromo-3,6-dichlorobenzaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Bromo-3,6-dichlorobenzaldehyde (CAS 1114809-26-5), molecular formula C7H3BrCl2O and molecular weight 253.91 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-Bromo-3,6-dichlorobenzaldehyde (C7H3BrCl2O) contains a hydroxyl group, an ether linkage, chlorine/bromine 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 253.91 g/mol, it falls into the medium-molecular-weight range. 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.
