Description
2S-t-Butyldimethylsilyloxy-3R-(t-Boc)-amino-1,4-dichlorobutane 326480-00-6 [(1R,2S)-3-Chloro-1-(chloromethyl)-2-[[(1,1-dimethylethyl)dimethylsilyl]oxy]propyl]carbamic Acid 1,1-Dimethylethyl Ester (CAS 326480-00-6), molecular formula C15H31Cl2NO3Si and molecular weight 372.40 g/mol, is a CATO reference standard with documented purity and traceability.
2S-t-Butyldimethylsilyloxy-3R-(t-Boc)-amino-1,4-dichlorobutane 326480-00-6 [(1R,2S)-3-Chloro-1-(chloromethyl)-2-[[(1,1-dimethylethyl)dimethylsilyl]oxy]propyl]carbamic Acid 1,1-Dimethylethyl Ester (C15H31Cl2NO3Si) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, 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.
