Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 605.07 g/mol gives Acid Red 95 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Acid Red 95 (CAS 33239-19-9) is a high-purity analytical reference standard with the molecular formula C20H8I2O5Na and a molecular weight of 605.07 g/mol.
The molecular framework of Acid Red 95 (C20H8I2O5Na) is characterized by a salt form, a flavonoid core, a hydroxyl group, an ether linkage, iodine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 Acid Red 95 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.
