2-Amino-1-(4-chloro-3-fluorophenyl)-4,5-dimethyl-1H-pyrrole-3-carbonitrile CAS 1308610-67-4

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.

2-Amino-1-(4-chloro-3-fluorophenyl)-4,5-dimethyl-1H-pyrrole-3-carbonitrile (CAS 1308610-67-4), molecular formula C13H11ClFN3 and molecular weight 263.70 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C13H11ClFN3, 2-Amino-1-(4-chloro-3-fluorophenyl)-4,5-dimethyl-1H-pyrrole-3-carbonitrile contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 263.70 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
