Chemical Structure

N'-{6-amino-5-hydroxy-1,3-dimethyl-2,4-dioxo-1H,2H,3H,4H-pyrido[2,3-d]pyrimidin-7-yl}benzohydrazide CAS 489434-43-7 chemical structure

Description

CATO supplies N'-{6-amino-5-hydroxy-1,3-dimethyl-2,4-dioxo-1H,2H,3H,4H-pyrido[2,3-d]pyrimidin-7-yl}benzohydrazide (CAS 489434-43-7), a certified reference material (molecular formula C16H16N6O4, MW 356.34 g/mol) for analytical method development and quality control.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, N'-{6-amino-5-hydroxy-1,3-dimethyl-2,4-dioxo-1H,2H,3H,4H-pyrido[2,3-d]pyrimidin-7-yl}benzohydrazide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 356.34 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 N'-{6-amino-5-hydroxy-1,3-dimethyl-2,4-dioxo-1H,2H,3H,4H-pyrido[2,3-d]pyrimidin-7-yl}benzohydrazide 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.
