Chemical Structure
Description
CATO supplies 5,6-Dimethyl-7h-pyrrolo[2,3-d]pyrimidin-4-ol (CAS 82703-35-3), a certified reference material (molecular formula C8H9N3O, MW 163.18 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 5,6-Dimethyl-7h-pyrrolo[2,3-d]pyrimidin-4-ol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 163.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
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 5,6-Dimethyl-7h-pyrrolo[2,3-d]pyrimidin-4-ol 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.
