Description

CATO supplies 3-iodanyl-4-methyl-benzenecarboximidamide 3-iodo-4-methylbenzenecarboximidamide 42872-79-7 A826043 (CAS 42872-79-7), a certified reference material (molecular formula C8H12IN, MW 249.09 g/mol) for analytical method development and quality control.

Structurally, 3-iodanyl-4-methyl-benzenecarboximidamide 3-iodo-4-methylbenzenecarboximidamide 42872-79-7 A826043 (C8H12IN) contains a nitrile group, iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 249.09 g/mol, it falls into the medium-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.

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.
