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 1-[(4-chlorophenyl)methyl]-2,5-dihydro-1H-pyrrole-2,5-dione.
1-[(4-chlorophenyl)methyl]-2,5-dihydro-1H-pyrrole-2,5-dione (CAS 34569-29-4) is a high-purity analytical reference standard with the molecular formula C11H8ClNO2 and a molecular weight of 221.64 g/mol.
1-[(4-chlorophenyl)methyl]-2,5-dihydro-1H-pyrrole-2,5-dione (C11H8ClNO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 1-[(4-chlorophenyl)methyl]-2,5-dihydro-1H-pyrrole-2,5-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.
