Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 204.22 g/mol gives 5,8-Dimethoxynaphthalen-1-ol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5,8-Dimethoxynaphthalen-1-ol (CAS 91963-30-3), molecular formula C12H12O3 and molecular weight 204.22 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 5,8-Dimethoxynaphthalen-1-ol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 204.22 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.
As a certified reference material (CRM), 5,8-Dimethoxynaphthalen-1-ol 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.
