Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,3-Diethyl 2-[(2-nitrophenyl)methylidene]propanedioate.
1,3-Diethyl 2-[(2-nitrophenyl)methylidene]propanedioate (CAS 17422-56-9), molecular formula C14H15NO6 and molecular weight 293.27 g/mol, is a CATO reference standard with documented purity and traceability.
1,3-Diethyl 2-[(2-nitrophenyl)methylidene]propanedioate (C14H15NO6) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 1,3-Diethyl 2-[(2-nitrophenyl)methylidene]propanedioate 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.
