4-Oxo-1H,2H,3H,3aH,4H,5H-pyrrolo[1,2-a]quinoxaline-7-carboxylic acid CAS 1008665-68-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Oxo-1H,2H,3H,3aH,4H,5H-pyrrolo[1,2-a]quinoxaline-7-carboxylic acid.

CATO supplies 4-Oxo-1H,2H,3H,3aH,4H,5H-pyrrolo[1,2-a]quinoxaline-7-carboxylic acid (CAS 1008665-68-6), a certified reference material (molecular formula C12H12N2O3, MW 232.24 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, 4-Oxo-1H,2H,3H,3aH,4H,5H-pyrrolo[1,2-a]quinoxaline-7-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 232.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), 4-Oxo-1H,2H,3H,3aH,4H,5H-pyrrolo[1,2-a]quinoxaline-7-carboxylic acid 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.
