Isocyanurate-based isophorone diisocyanate trimer CAS 67873-91-0

Description

Compared with other compounds in its class, the molecular weight of 666.85 g/mol gives Isocyanurate-based isophorone diisocyanate trimer distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Isocyanurate-based isophorone diisocyanate trimer (CAS 67873-91-0), molecular formula C36H54N6O6 and molecular weight 666.85 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Isocyanurate-based isophorone diisocyanate trimer (C36H54N6O6) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
