Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Gram′s Iodine.
Gram′s Iodine (CAS 12298-68-9), molecular formula I3K and molecular weight 419.80 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a salt form, iodine substitution, Gram′s Iodine is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 419.80 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Gram′s Iodine 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.
