The occurrence of Benzene-d1 is closely related to deuterium isotope labeling, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Benzene-d1 (CAS 1120-89-4), molecular formula C6H5D and molecular weight 79.12 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to deuterium isotope labeling, an aromatic ring system, Benzene-d1 is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 79.12 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.
As a certified reference material (CRM), Benzene-d1 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.
