Description
(1->4)-3,6-anhydro-2-O-sulfonato-alpha-D-galactopyranosyl-(1->3)-4-O-sulfonato-beta-D-galactopyranan 9062-07-1 CHEBI:37168 iota-carrageenan (CAS 9062-07-1) is a high-purity analytical reference standard with the molecular formula C24H34O31S4 and a molecular weight of 946.77 g/mol.
Structurally, (1->4)-3,6-anhydro-2-O-sulfonato-alpha-D-galactopyranosyl-(1->3)-4-O-sulfonato-beta-D-galactopyranan 9062-07-1 CHEBI:37168 iota-carrageenan (C24H34O31S4) contains a flavonoid core, a sulfone group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 946.77 g/mol, it falls into the high-molecular-weight range. 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.
As a certified reference material (CRM), (1->4)-3,6-anhydro-2-O-sulfonato-alpha-D-galactopyranosyl-(1->3)-4-O-sulfonato-beta-D-galactopyranan 9062-07-1 CHEBI:37168 iota-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.
