Chemical Structure
Description
1,4-Bis(2-(3,4-diethoxybenzylidene)hydrazinyl)phthalazine (CAS 27704-11-6), molecular formula C30H34N6O4 and molecular weight 542.63 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1,4-Bis(2-(3,4-diethoxybenzylidene)hydrazinyl)phthalazine (C30H34N6O4) is characterized by a steroid 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. 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 1,4-Bis(2-(3,4-diethoxybenzylidene)hydrazinyl)phthalazine 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.
