Chemical Structure
Description
Owing to a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system, 1-(Chloromethyl)-2-((o-tolyloxy)methyl)benzene is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 246.73 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.
1-(Chloromethyl)-2-((o-tolyloxy)methyl)benzene (CAS 156489-68-8), molecular formula C15H15ClO and molecular weight 246.73 g/mol, is a CATO reference standard with documented purity and traceability.
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.
