Chemical Structure

κ--carrageenan CAS 11114-20-8 chemical structure

Description

The occurrence of κ--carrageenan is closely related to a structurally diverse molecular composition in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies κ--carrageenan (CAS 11114-20-8), a certified reference material (molecular formula N/A, MW 386.33 g/mol) for analytical method development and quality control.

κ--carrageenan is supplied as a fully characterized reference material; its structural identity, assigned purity, and stability data are documented in the batch-specific Certificate of Analysis (COA).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), κ--carrageenan 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.
