25189-55-3 CHEBI:53234 N-(1-Methylethyl)-2-propenamide homopolymer PNIPAAm PNIPAM Poly-N-isopropylacrylamide poly(N-isopropyl-acrylamide) poly(N-isopropylacrylamide) poly(N-isopropylacrylamide) macromolecule poly(NIPAM) poly[1-(isopropylcarbamoyl)ethylene] CAS 25189-55-3 chemical structure

Description

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.

25189-55-3 CHEBI:53234 N-(1-Methylethyl)-2-propenamide homopolymer PNIPAAm PNIPAM Poly-N-isopropylacrylamide poly(N-isopropyl-acrylamide) poly(N-isopropylacrylamide) poly(N-isopropylacrylamide) macromolecule poly(NIPAM) poly[1-(isopropylcarbamoyl)ethylene] (CAS 25189-55-3) is a high-purity analytical reference standard with the molecular formula C6H11NO and a molecular weight of 113.16 g/mol.

Owing to an amide group, a hydroxyl group, an ether linkage, 25189-55-3 CHEBI:53234 N-(1-Methylethyl)-2-propenamide homopolymer PNIPAAm PNIPAM Poly-N-isopropylacrylamide poly(N-isopropyl-acrylamide) poly(N-isopropylacrylamide) poly(N-isopropylacrylamide) macromolecule poly(NIPAM) poly[1-(isopropylcarbamoyl)ethylene] is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 113.16 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.
