Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 2,3-Dibromo-4-((2-chlorobenzyl)oxy)-5-ethoxybenzaldehyde (CAS 832674-51-8), a certified reference material (molecular formula C16H13Br2ClO3, MW 448.53 g/mol) for analytical method development and quality control.
Structurally, 2,3-Dibromo-4-((2-chlorobenzyl)oxy)-5-ethoxybenzaldehyde (C16H13Br2ClO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine 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 448.53 g/mol, it falls into the moderately-high-molecular-weight range. 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.
