Chemical Structure

Naphthalene-1-Aldehyde CAS 66-77-3 chemical structure

Description

The molecular framework of Naphthalene-1-Aldehyde (C11H8O) is characterized by a hydroxyl group, an ether linkage, an aromatic ring 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).

Naphthalene-1-Aldehyde (CAS 66-77-3) is a high-purity analytical reference standard with the molecular formula C11H8O and a molecular weight of 156.18 g/mol.

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 Naphthalene-1-Aldehyde 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.
