Chemical Structure

(R)-tert-Butyl (4-bromobutan-2-yl)carbamate CAS 106622-19-9 chemical structure

Description

The occurrence of (R)-tert-Butyl (4-bromobutan-2-yl)carbamate is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (R)-tert-Butyl (4-bromobutan-2-yl)carbamate (CAS 106622-19-9), a certified reference material (molecular formula C9H18BrNO2, MW 252.15 g/mol) for analytical method development and quality control.

Structurally, (R)-tert-Butyl (4-bromobutan-2-yl)carbamate (C9H18BrNO2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. 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 252.15 g/mol, it falls into the medium-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.
