Description
CATO manufactures 3-Amino-1-propanesulfonic Acid 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.
3-Amino-1-propanesulfonic Acid (CAS 3687-70-5), molecular formula C25H20Cl2PCl and molecular weight 457.76 g/mol, is a CATO reference standard with documented purity and traceability.
3-Amino-1-propanesulfonic Acid (C25H20Cl2PCl) contains organophosphorus functionality, chlorine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
