Chemical Structure

Poly(N-vinyl caprolactam) CAS 25189-83-7 chemical structure

Description

As a certified reference material (CRM), Poly(N-vinyl caprolactam) meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

Poly(N-vinyl caprolactam) (CAS 25189-83-7), molecular formula C8H13NO and molecular weight 139.19 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Poly(N-vinyl caprolactam) (C8H13NO) is characterized by an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
