Chemical Structure

Tert-butyl (2R,4S)-4-((tert-butyldimethylsilyl)oxy)-2-methylpyrrolidine-1-carboxylate CAS 1642786-63-7 chemical structure

Description

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.

Tert-butyl (2R,4S)-4-((tert-butyldimethylsilyl)oxy)-2-methylpyrrolidine-1-carboxylate (CAS 1642786-63-7), molecular formula C16H33NO3Si and molecular weight 315.52 g/mol, is a CATO reference standard with documented purity and traceability.

Tert-butyl (2R,4S)-4-((tert-butyldimethylsilyl)oxy)-2-methylpyrrolidine-1-carboxylate (C16H33NO3Si) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage. 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
