Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 3,5-Diiodo-<SC>L</SC>-tyrosine dihydrate (CAS 18835-59-1), a certified reference material (molecular formula C9H15I2NO3, MW 439.03 g/mol) for analytical method development and quality control.
Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, 3,5-Diiodo-<SC>L</SC>-tyrosine dihydrate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 439.03 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 3,5-Diiodo-<SC>L</SC>-tyrosine dihydrate 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.
