Chemical Structure

Biphenyl-4,4′-d2 CAS 6120-99-6 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 156.22 g/mol gives Biphenyl-4,4′-d2 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Biphenyl-4,4′-d2 (CAS 6120-99-6), molecular formula C12H8D2 and molecular weight 156.22 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Biphenyl-4,4′-d2 (C12H8D2) contains deuterium isotope labeling, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 156.22 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
