Chemical Structure
Description
1,3-Diethyl 2-[2-(3-nitrophenyl)hydrazin-1-ylidene]propanedioate (CAS 13631-94-2), molecular formula C13H15N3O6 and molecular weight 309.27 g/mol, is a CATO reference standard with documented purity and traceability.
1,3-Diethyl 2-[2-(3-nitrophenyl)hydrazin-1-ylidene]propanedioate (C13H15N3O6) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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-(3-nitrophenyl)hydrazin-1-ylidene]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.
