(1,3-Diisopropyl-1,3-dihydro-2H-benzo[d]imidazol-2-ylidene)gold(III) chloride CAS 953820-59-2

Description

The occurrence of (1,3-Diisopropyl-1,3-dihydro-2H-benzo[d]imidazol-2-ylidene)gold(III) chloride is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(1,3-Diisopropyl-1,3-dihydro-2H-benzo[d]imidazol-2-ylidene)gold(III) chloride (CAS 953820-59-2), molecular formula C13H18AuClN2 and molecular weight 434.71 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (1,3-Diisopropyl-1,3-dihydro-2H-benzo[d]imidazol-2-ylidene)gold(III) chloride (C13H18AuClN2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 5.5, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 434.71 g/mol, it falls into the moderately-high-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.

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.
