2-Chloro-4-[3-iodo-1-(1-methylethyl)-1H-pyrazol-4-yl]pyrimidine CAS 1269440-58-5

Description

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/iodine substitution, 2-Chloro-4-[3-iodo-1-(1-methylethyl)-1H-pyrazol-4-yl]pyrimidine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 348.57 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

2-Chloro-4-[3-iodo-1-(1-methylethyl)-1H-pyrazol-4-yl]pyrimidine (CAS 1269440-58-5), molecular formula C10H10ClIN4 and molecular weight 348.57 g/mol, is a CATO reference standard with documented purity and traceability.

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.
