Chemical Structure
Description
The occurrence of Sodium Chondroitin Sulfate A is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Sodium Chondroitin Sulfate A (CAS 39455-18-0) is a high-purity analytical reference standard with the molecular formula (C14H₂₃NO15S)nxNa and a molecular weight of 478.20 g/mol.
The molecular framework of Sodium Chondroitin Sulfate A ((C14H₂₃NO15S)nxNa) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 Sodium Chondroitin Sulfate A 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.
