Chemical Structure
Description
4-Formyl-2-methoxyphenyl 1-naphthoate (CAS 357159-67-2) is a high-purity analytical reference standard with the molecular formula C19H14O4 and a molecular weight of 306.31 g/mol.
4-Formyl-2-methoxyphenyl 1-naphthoate (C19H14O4) contains a flavonoid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 4-Formyl-2-methoxyphenyl 1-naphthoate 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.
