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.
Carbamic acid, [4-?[[(2-?methoxyethoxy)?acetyl]?amino]?phenyl]?-?, 1,?1-?dimethylethyl ester 851652-00-1 A1-01314 (CAS 851652-00-1) is a high-purity analytical reference standard with the molecular formula C16H24N2O5 and a molecular weight of 324.37 g/mol.
Based on its molecular formula C16H24N2O5, Carbamic acid, [4-?[[(2-?methoxyethoxy)?acetyl]?amino]?phenyl]?-?, 1,?1-?dimethylethyl ester 851652-00-1 A1-01314 contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 324.37 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.
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.
