Chemical Structure
Description
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.
Dimethyl((3S)-4,4-dimethyl-3-(Boc-amino)-2-oxopentyl)-phosphonate (Q-2145.0250) (CAS 176504-89-5), molecular formula C14H28NO6P and molecular weight 337.35 g/mol, is a CATO reference standard with documented purity and traceability.
Dimethyl((3S)-4,4-dimethyl-3-(Boc-amino)-2-oxopentyl)-phosphonate (Q-2145.0250) (C14H28NO6P) contains an amide group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
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.
