Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

Methyl (3-iodo-7-oxo-6,7-dihydro-1H-pyrazolo[4,3-d]pyrimidin-5-yl)carbamate (CAS 2679840-45-8) is a high-purity analytical reference standard with the molecular formula C7H6IN5O3 and a molecular weight of 335.06 g/mol.

The molecular framework of Methyl (3-iodo-7-oxo-6,7-dihydro-1H-pyrazolo[4,3-d]pyrimidin-5-yl)carbamate (C7H6IN5O3) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

CATO manufactures Methyl (3-iodo-7-oxo-6,7-dihydro-1H-pyrazolo[4,3-d]pyrimidin-5-yl)carbamate 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.
