Description

Compared with other compounds in its class, the molecular weight of 279.35 g/mol gives 2-(N-3-Sulfopropyl-N,N-dimethyl ammonium)ethyl methacrylate 3637-26-1 N-(3-Sulfopropyl)-N-(methacryloxyethyl)-N,N-dimethylammonium betaine [2-(Methacryloyloxy)ethyl]dimethyl-(3-sulfopropyl)ammonium hydroxide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-(N-3-Sulfopropyl-N,N-dimethyl ammonium)ethyl methacrylate 3637-26-1 N-(3-Sulfopropyl)-N-(methacryloxyethyl)-N,N-dimethylammonium betaine [2-(Methacryloyloxy)ethyl]dimethyl-(3-sulfopropyl)ammonium hydroxide (CAS 3637-26-1) is a high-purity analytical reference standard with the molecular formula C11H21NO5S and a molecular weight of 279.35 g/mol.

Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 2-(N-3-Sulfopropyl-N,N-dimethyl ammonium)ethyl methacrylate 3637-26-1 N-(3-Sulfopropyl)-N-(methacryloxyethyl)-N,N-dimethylammonium betaine [2-(Methacryloyloxy)ethyl]dimethyl-(3-sulfopropyl)ammonium hydroxide is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 279.35 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.

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.
