Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
SKF 83822 Hydrobromide (CAS 74115-10-9) is a high-purity analytical reference standard with the molecular formula C20H22ClNO2HBr and a molecular weight of 424.76 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, SKF 83822 Hydrobromide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 424.76 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures SKF 83822 Hydrobromide 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.
