Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies Ethyl 1-hydroxy-6-methoxy-2-naphthoate (CAS 690232-01-0), a certified reference material (molecular formula C14H14O4, MW 246.26 g/mol) for analytical method development and quality control.
The molecular framework of Ethyl 1-hydroxy-6-methoxy-2-naphthoate (C14H14O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), Ethyl 1-hydroxy-6-methoxy-2-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.
