Chemical Structure
Description
2-(Boc-amino)-2-(3,4-dichlorophenyl)acetic Acid (CAS 142121-95-7) is a high-purity analytical reference standard with the molecular formula C13H15Cl2NO4 and a molecular weight of 320.17 g/mol.
2-(Boc-amino)-2-(3,4-dichlorophenyl)acetic Acid (C13H15Cl2NO4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.
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.
