Chemical Structure
Description
2,4-Dichloro-7-methylpyrrolo[2,1-f][1,2,4]triazine (C7H5Cl2N3) contains a nitrile group, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
2,4-Dichloro-7-methylpyrrolo[2,1-f][1,2,4]triazine (CAS 1613751-73-7), molecular formula C7H5Cl2N3 and molecular weight 202.04 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
