Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Propyl-1-(4-(pyrrolidin-1-yl)but-2-yn-1-yl)quinazoline-2,4(1H,3H)-dione oxalate.
3-Propyl-1-(4-(pyrrolidin-1-yl)but-2-yn-1-yl)quinazoline-2,4(1H,3H)-dione oxalate (CAS 23905-26-2), molecular formula C19H23N3O2C2H2O4 and molecular weight 415.45 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-Propyl-1-(4-(pyrrolidin-1-yl)but-2-yn-1-yl)quinazoline-2,4(1H,3H)-dione oxalate (C19H23N3O2C2H2O4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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 3-Propyl-1-(4-(pyrrolidin-1-yl)but-2-yn-1-yl)quinazoline-2,4(1H,3H)-dione oxalate 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.
