CATO supplies 1076198-55-4 N-(2-Methyl-5-nitrophenyl)-N-[4-(3-pyridinyl)-2-pyrimidinyl]carbamic Acid 1,1-Dimethylethyl Ester N-(2-Methyl-5-nitrophenyl)-N-[4-pyridin-3-yl-pyrimidin-2-yl]-t-boc (CAS 1076198-55-4), a certified reference material (molecular formula C21H21N5O4, MW 407.42 g/mol) for analytical method development and quality control.
Structurally, 1076198-55-4 N-(2-Methyl-5-nitrophenyl)-N-[4-(3-pyridinyl)-2-pyrimidinyl]carbamic Acid 1,1-Dimethylethyl Ester N-(2-Methyl-5-nitrophenyl)-N-[4-pyridin-3-yl-pyrimidin-2-yl]-t-boc (C21H21N5O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 407.42 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1076198-55-4 N-(2-Methyl-5-nitrophenyl)-N-[4-(3-pyridinyl)-2-pyrimidinyl]carbamic Acid 1,1-Dimethylethyl Ester N-(2-Methyl-5-nitrophenyl)-N-[4-pyridin-3-yl-pyrimidin-2-yl]-t-boc 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.
