Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 241.45 g/mol gives Pyridine Iodine Monochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Pyridine Iodine Monochloride (CAS 6443-90-9), a certified reference material (molecular formula ClIC5H5N, MW 241.45 g/mol) for analytical method development and quality control.
Structurally, Pyridine Iodine Monochloride (ClIC5H5N) contains a nitrile group, chlorine/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 241.45 g/mol, it falls into the medium-molecular-weight range. 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.
CATO manufactures Pyridine Iodine Monochloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
