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.
(E)-4-(Dimethylamino)but-2-enoyl chloride hydrochloride (CAS 1055943-40-2), molecular formula C6H10ClNOHCl and molecular weight 184.06 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C6H10ClNOHCl, (E)-4-(Dimethylamino)but-2-enoyl chloride hydrochloride contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 184.06 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
