4-(tert-Butylamino)-2-chloro-1,1,1-trifluoro-but-2-ene CAS 191591-45-4 chemical structure

Description

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.

4-(tert-Butylamino)-2-chloro-1,1,1-trifluoro-but-2-ene (CAS 191591-45-4) is a high-purity analytical reference standard with the molecular formula C8H13ClF3N and a molecular weight of 215.64 g/mol.

Owing to fluorine/chlorine substitution, 4-(tert-Butylamino)-2-chloro-1,1,1-trifluoro-but-2-ene is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 215.64 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
