Chemical Structure
Description
Iodo(triethyl phosphite)copper(I) (CAS 51717-23-8), molecular formula CuIC6H15O3P and molecular weight 356.60 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a salt form, a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, Iodo(triethyl phosphite)copper(I) is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 356.60 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 Iodo(triethyl phosphite)copper(I) 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.
