1076199-67-1 3-(tert-Butyldimethylsilyloxy)-5-(1-methylamino)-5-oxopentanoic Acid Methyl Ester 3-[(1,1-Dimethylethyl)dimethylsilyloxy]-5-(1-methylamino)-5-oxopentanoic Acid Methyl Ester (CAS 1076199-67-1), molecular formula C13H27NO4Si and molecular weight 289.44 g/mol, is a CATO reference standard with documented purity and traceability.
1076199-67-1 3-(tert-Butyldimethylsilyloxy)-5-(1-methylamino)-5-oxopentanoic Acid Methyl Ester 3-[(1,1-Dimethylethyl)dimethylsilyloxy]-5-(1-methylamino)-5-oxopentanoic Acid Methyl Ester (C13H27NO4Si) contains an amide 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.
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.
