Chemical Structure
Description
Pentachlorophenyl(tetrahydrothiophene)gold (CAS 71521-30-7) is a high-purity analytical reference standard with the molecular formula C10H7Cl5SAu and a molecular weight of 533.45 g/mol.
Structurally, Pentachlorophenyl(tetrahydrothiophene)gold (C10H7Cl5SAu) contains sulfur-containing functionality, chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 533.45 g/mol, it falls into the moderately-high-molecular-weight range. 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), Pentachlorophenyl(tetrahydrothiophene)gold 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.
