2-((4-(3-Chloropropanoyl)-3,4-dihydroquinoxalin-1(2H)-yl)methylene)malononitrile CAS 6687-90-7 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-((4-(3-Chloropropanoyl)-3,4-dihydroquinoxalin-1(2H)-yl)methylene)malononitrile.

CATO supplies 2-((4-(3-Chloropropanoyl)-3,4-dihydroquinoxalin-1(2H)-yl)methylene)malononitrile (CAS 6687-90-7), a certified reference material (molecular formula C15H13ClN4O, MW 300.74 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, chlorine substitution, 2-((4-(3-Chloropropanoyl)-3,4-dihydroquinoxalin-1(2H)-yl)methylene)malononitrile is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 300.74 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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), 2-((4-(3-Chloropropanoyl)-3,4-dihydroquinoxalin-1(2H)-yl)methylene)malononitrile 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.
