Description

The occurrence of 2-((2,6-Dichlorobenzyl)oxy)-5-methylbenzaldehyde is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-((2,6-Dichlorobenzyl)oxy)-5-methylbenzaldehyde (CAS 1272179-81-3), molecular formula C15H12Cl2O2 and molecular weight 295.16 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-((2,6-Dichlorobenzyl)oxy)-5-methylbenzaldehyde (C15H12Cl2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 295.16 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.
