2-(Chloromethyl)-3-cyano-5-(difluoromethyl)-4-iodopyridine CAS 1806979-55-4

Description

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.

2-(Chloromethyl)-3-cyano-5-(difluoromethyl)-4-iodopyridine (CAS 1806979-55-4), molecular formula C8H4ClF2IN2 and molecular weight 328.49 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-(Chloromethyl)-3-cyano-5-(difluoromethyl)-4-iodopyridine (C8H4ClF2IN2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine/iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 328.49 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.

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.
