Chemical Structure
Description
The occurrence of 1-Methyl-3-nitro-1H-pyrrole is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-Methyl-3-nitro-1H-pyrrole (CAS 823-72-3), molecular formula C5H6N2O2 and molecular weight 126.11 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 1-Methyl-3-nitro-1H-pyrrole is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 126.11 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
