The occurrence of Methyl 2-bromo-2-((tert-butoxycarbonyl)amino)acetate is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Methyl 2-bromo-2-((tert-butoxycarbonyl)amino)acetate (CAS 138219-39-3), molecular formula C8H14BrNO4 and molecular weight 268.11 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C8H14BrNO4, Methyl 2-bromo-2-((tert-butoxycarbonyl)amino)acetate contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 268.11 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
