Chemical Structure
Description
CATO supplies 6-Oxo-1,2-dihydro-6H-pyrrolo[3,2,1-ij]quinoline-5-carbohydrazide (CAS 57771-94-5), a certified reference material (molecular formula C12H11N3O2, MW 229.23 g/mol) for analytical method development and quality control.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 6-Oxo-1,2-dihydro-6H-pyrrolo[3,2,1-ij]quinoline-5-carbohydrazide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 229.23 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.
As a certified reference material (CRM), 6-Oxo-1,2-dihydro-6H-pyrrolo[3,2,1-ij]quinoline-5-carbohydrazide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
