Chemical Structure

2,3,5,6-tetradeuterioterephthalonitrile CAS 69299-69-0 chemical structure

Description

Owing to deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, a nitrile group, 2,3,5,6-tetradeuterioterephthalonitrile is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 138.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

2,3,5,6-tetradeuterioterephthalonitrile (CAS 69299-69-0) is a high-purity analytical reference standard with the molecular formula C8H6D4N2 and a molecular weight of 138.20 g/mol.

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.

As a certified reference material (CRM), 2,3,5,6-tetradeuterioterephthalonitrile meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
