(3S,4R,5S)-4-((tert-butoxycarbonyl)amino)-3-((tert-butyldimethylsilyl)oxy)-5-methylheptanoic acid CAS 110720-45-1 chemical structure

Description

The occurrence of (3S,4R,5S)-4-((tert-butoxycarbonyl)amino)-3-((tert-butyldimethylsilyl)oxy)-5-methylheptanoic acid is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(3S,4R,5S)-4-((tert-butoxycarbonyl)amino)-3-((tert-butyldimethylsilyl)oxy)-5-methylheptanoic acid (CAS 110720-45-1) is a high-purity analytical reference standard with the molecular formula C19H39NO5Si and a molecular weight of 389.60 g/mol.

Structurally, (3S,4R,5S)-4-((tert-butoxycarbonyl)amino)-3-((tert-butyldimethylsilyl)oxy)-5-methylheptanoic acid (C19H39NO5Si) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 389.60 g/mol, it falls into the moderately-high-molecular-weight range. 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.
