Chemical Structure

1,8-dihydroxynaphthalene-2-carbaldehyde CAS 858457-19-9 chemical structure

Description

The molecular framework of 1,8-dihydroxynaphthalene-2-carbaldehyde (C11H18O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

1,8-dihydroxynaphthalene-2-carbaldehyde (CAS 858457-19-9), molecular formula C11H18O3 and molecular weight 198.26 g/mol, is a CATO reference standard with documented purity and traceability.

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.

CATO manufactures 1,8-dihydroxynaphthalene-2-carbaldehyde under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
