2-AMINO-5-NITRO-4-PICOLINE 2-Amino-4-methyl-5-nitropyridine 21901-40-6 4-METHYL-5-NITRO-2-PYRIDINAMINE 4-METHYL-5-NITRO-2-PYRIDYLAMINE 4-METHYL-5-NITRO-PYRIDIN-2-YLAMINE AS04891 (CAS 21901-40-6) is a high-purity analytical reference standard with the molecular formula C6H13N3O2 and a molecular weight of 159.19 g/mol.
2-AMINO-5-NITRO-4-PICOLINE 2-Amino-4-methyl-5-nitropyridine 21901-40-6 4-METHYL-5-NITRO-2-PYRIDINAMINE 4-METHYL-5-NITRO-2-PYRIDYLAMINE 4-METHYL-5-NITRO-PYRIDIN-2-YLAMINE AS04891 (C6H13N3O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), 2-AMINO-5-NITRO-4-PICOLINE 2-Amino-4-methyl-5-nitropyridine 21901-40-6 4-METHYL-5-NITRO-2-PYRIDINAMINE 4-METHYL-5-NITRO-2-PYRIDYLAMINE 4-METHYL-5-NITRO-PYRIDIN-2-YLAMINE AS04891 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
