Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3-Chloro-4-[(4-chlorobenzyl)oxy]-5-ethoxybenzaldehyde (CAS 384857-10-7), molecular formula C16H14Cl2O3 and molecular weight 325.19 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C16H14Cl2O3, 3-Chloro-4-[(4-chlorobenzyl)oxy]-5-ethoxybenzaldehyde contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 325.19 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
