5-Ethylisophthalaldehyde CAS 118792-76-0 chemical structure

Description

5-Ethylisophthalaldehyde (CAS 118792-76-0) is a high-purity analytical reference standard with the molecular formula C10H10O2 and a molecular weight of 162.19 g/mol.

Based on its molecular formula C10H10O2, 5-Ethylisophthalaldehyde contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 162.19 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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 5-Ethylisophthalaldehyde 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.
