Description

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.

CATO supplies BUS4P4I6FX 90217-02-0 5-Cyano-2,3-di-p-tolyltetrazolium chloride 5-Cyano-2,3-ditolyltetrazolium 2H-Tetrazolium, 5-cyano-2,3-bis(4-methylphenyl)-, chloride CTC UNII-BUS4P4I6FX 5-Cyano-2,3-ditolyltetrazolium chloride (CAS 90217-02-0), a certified reference material (molecular formula C16H29N5Cl, MW 326.89 g/mol) for analytical method development and quality control.

Structurally, BUS4P4I6FX 90217-02-0 5-Cyano-2,3-di-p-tolyltetrazolium chloride 5-Cyano-2,3-ditolyltetrazolium 2H-Tetrazolium, 5-cyano-2,3-bis(4-methylphenyl)-, chloride CTC UNII-BUS4P4I6FX 5-Cyano-2,3-ditolyltetrazolium chloride (C16H29N5Cl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.5, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 326.89 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
