Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Tetrakis[4-(iodo)phenyl]methane (CAS 134080-67-4), molecular formula C25H16I4 and molecular weight 824.01 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Tetrakis[4-(iodo)phenyl]methane (C25H16I4) contains iodine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 16.0, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 824.01 g/mol, it falls into the 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).
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.
