Chemical Structure

5-Methyl-1-naphthol CAS 51149-87-2 chemical structure

Description

As a certified reference material (CRM), 5-Methyl-1-naphthol 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.

5-Methyl-1-naphthol (CAS 51149-87-2), molecular formula C11H10O and molecular weight 158.20 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a hydroxyl group, an ether linkage, an aromatic ring system, 5-Methyl-1-naphthol is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 158.20 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.

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.
