Chemical Structure
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.
3-(3-Iodophenyl)-4-methyl-1h-pyrazol-5-amine (CAS 2145467-70-3), molecular formula C10H10IN3 and molecular weight 299.11 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-(3-Iodophenyl)-4-methyl-1h-pyrazol-5-amine (C10H10IN3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, iodine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
