Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Fluoro-4-methylnaphthalene.
1-Fluoro-4-methylnaphthalene (CAS 315-50-4), molecular formula C11H9F and molecular weight 160.19 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to fluorine substitution, an aromatic ring system, 1-Fluoro-4-methylnaphthalene is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 160.19 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), 1-Fluoro-4-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.
