Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 304.21 g/mol gives N-[4-(2,3-Dichlorophenyl)-3,4-dihydro-1(2H)-naphthalenylidene]methanamine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
N-[4-(2,3-Dichlorophenyl)-3,4-dihydro-1(2H)-naphthalenylidene]methanamine (CAS 340830-05-9) is a high-purity analytical reference standard with the molecular formula C17H15Cl2N and a molecular weight of 304.21 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, N-[4-(2,3-Dichlorophenyl)-3,4-dihydro-1(2H)-naphthalenylidene]methanamine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 304.21 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.
