Chemical Structure
Description
2,5-Bis((2-hexyldecyl)oxy)terephthalaldehyde (CAS 2136615-87-5), molecular formula C40H70O4 and molecular weight 614.98 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C40H70O4, 2,5-Bis((2-hexyldecyl)oxy)terephthalaldehyde 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 614.98 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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 2,5-Bis((2-hexyldecyl)oxy)terephthalaldehyde 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.
