Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
1-(4-Chloronaphthalen-1-yl)-N-methylmethanamine (CAS 98978-51-9), molecular formula C12H12ClN and molecular weight 205.68 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 1-(4-Chloronaphthalen-1-yl)-N-methylmethanamine is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 205.68 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), 1-(4-Chloronaphthalen-1-yl)-N-methylmethanamine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
