Quininesalicylate CAS 750-90-3 chemical structure

Description

CATO manufactures Quininesalicylate 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.

Quininesalicylate (CAS 750-90-3) is a high-purity analytical reference standard with the molecular formula C28H36Cl2N4O4S and a molecular weight of 595.58 g/mol.

Based on its molecular formula C28H36Cl2N4O4S, Quininesalicylate contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 595.58 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
