Description

Compared with other compounds in its class, the molecular weight of 1540.24 g/mol gives (12E,14E,21E)-2,3,9,10,16,17,23,24-octakis(octyloxy)-13H,29H-phthalocyanine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(12E,14E,21E)-2,3,9,10,16,17,23,24-octakis(octyloxy)-13H,29H-phthalocyanine (CAS 119457-81-7) is a high-purity analytical reference standard with the molecular formula C96H146N8O8 and a molecular weight of 1540.24 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, (12E,14E,21E)-2,3,9,10,16,17,23,24-octakis(octyloxy)-13H,29H-phthalocyanine is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 1540.24 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.
