Chemical Structure
Description
The occurrence of Gold(I) potassium cyanide is closely related to an organic framework in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Gold(I) potassium cyanide (CAS 13967-50-5), molecular formula AuKCN and molecular weight 262.09 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an organic framework, Gold(I) potassium cyanide is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 262.09 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
