Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 1177.74 g/mol gives Tri(n-octyl-n-decyl) trimellitate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Tri(n-octyl-n-decyl) trimellitate (CAS 67989-23-5), molecular formula C39H66O6C33H54O6 and molecular weight 1177.74 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, Tri(n-octyl-n-decyl) trimellitate is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 1177.74 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 Tri(n-octyl-n-decyl) trimellitate 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.
