Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 262.14 g/mol gives tert-Butyl (2-bromoethyl)(prop-2-yn-1-yl)carbamate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies tert-Butyl (2-bromoethyl)(prop-2-yn-1-yl)carbamate (CAS 2142567-32-4), a certified reference material (molecular formula C10H16BrNO2, MW 262.14 g/mol) for analytical method development and quality control.
Structurally, tert-Butyl (2-bromoethyl)(prop-2-yn-1-yl)carbamate (C10H16BrNO2) 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 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 262.14 g/mol, it falls into the medium-molecular-weight range. 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.
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.
