Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 6-bromo-3-methyl-2-oxo-2,3-dihydro-1H-1,3-benzodiazole-1-carboxylate.
Ethyl 6-bromo-3-methyl-2-oxo-2,3-dihydro-1H-1,3-benzodiazole-1-carboxylate (CAS 339013-60-4) is a high-purity analytical reference standard with the molecular formula C11H11BrN2O3 and a molecular weight of 299.12 g/mol.
Based on its molecular formula C11H11BrN2O3, Ethyl 6-bromo-3-methyl-2-oxo-2,3-dihydro-1H-1,3-benzodiazole-1-carboxylate contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 299.12 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
As a certified reference material (CRM), Ethyl 6-bromo-3-methyl-2-oxo-2,3-dihydro-1H-1,3-benzodiazole-1-carboxylate 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.
