Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 260.72 g/mol gives 5-Chloro-2-((2-methylbenzyl)oxy)benzaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-Chloro-2-((2-methylbenzyl)oxy)benzaldehyde (CAS 590360-24-0), molecular formula C15H13ClO2 and molecular weight 260.72 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system, 5-Chloro-2-((2-methylbenzyl)oxy)benzaldehyde is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 260.72 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
