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 4-((1-Methyl-1H-pyrrol-2-yl)methylene)isoquinoline-1,3(2H,4H)-dione.
4-((1-Methyl-1H-pyrrol-2-yl)methylene)isoquinoline-1,3(2H,4H)-dione (CAS 1104546-89-5), molecular formula C15H12N2O2 and molecular weight 252.27 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 4-((1-Methyl-1H-pyrrol-2-yl)methylene)isoquinoline-1,3(2H,4H)-dione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 252.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 4-((1-Methyl-1H-pyrrol-2-yl)methylene)isoquinoline-1,3(2H,4H)-dione 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.
