Chemical Structure
Description
The occurrence of λ-Carrageenan (Low-viscosity) is closely related to a carbohydrate-derived structure, a sulfone group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
λ-Carrageenan (Low-viscosity) (CAS 9064-57-7), molecular formula C12H19O20S3 and molecular weight 579.46 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of λ-Carrageenan (Low-viscosity) (C12H19O20S3) is characterized by a carbohydrate-derived structure, a sulfone group. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures λ-Carrageenan (Low-viscosity) under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
