Description
CATO manufactures Arsenic disulfide 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.
Arsenic disulfide (CAS 1303-32-8), molecular formula As2S2 and molecular weight 213.97 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Arsenic disulfide (As2S2) is characterized by sulfur-containing functionality. 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
