Hexamethylbenzene-d18 CAS 4342-40-9

Description

Compared with other compounds in its class, the molecular weight of 180.38 g/mol gives Hexamethylbenzene-d18 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Hexamethylbenzene-d18 (CAS 4342-40-9) is a high-purity analytical reference standard with the molecular formula C12D18 and a molecular weight of 180.38 g/mol.

Structurally, Hexamethylbenzene-d18 (C12D18) contains deuterium isotope labeling, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 180.38 g/mol, it falls into the medium-molecular-weight range. 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.

As a certified reference material (CRM), Hexamethylbenzene-d18 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.
