8-Hydroxy-2-Naphthalenecarboxaldehyde CAS 1261638-22-5

Description

Compared with other compounds in its class, the molecular weight of 172.18 g/mol gives 8-Hydroxy-2-Naphthalenecarboxaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

8-Hydroxy-2-Naphthalenecarboxaldehyde (CAS 1261638-22-5), molecular formula C11H8O2 and molecular weight 172.18 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 8-Hydroxy-2-Naphthalenecarboxaldehyde is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 172.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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 8-Hydroxy-2-Naphthalenecarboxaldehyde 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.
