1-Methyl-4,5-dinitro-1H-imidazole CAS 19183-15-4

Description

The occurrence of 1-Methyl-4,5-dinitro-1H-imidazole is closely related to a carbohydrate-derived structure, an amide group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-Methyl-4,5-dinitro-1H-imidazole (CAS 19183-15-4), molecular formula C4H4N4O4 and molecular weight 172.10 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carbohydrate-derived structure, an amide group, 1-Methyl-4,5-dinitro-1H-imidazole is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 172.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

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.
