Chemical Structure
Description
1-Allyl-2-methylnaphthalene (CAS 23116-22-5), molecular formula C14H14 and molecular weight 182.26 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a polycyclic aromatic system, 1-Allyl-2-methylnaphthalene is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 182.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
As a certified reference material (CRM), 1-Allyl-2-methylnaphthalene 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.
