Chemical Structure
Description
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
2-(2-(3,4,5-Trimethoxybenzoyl)hydrazine-1-carbonyl)benzoic acid (CAS 356526-74-4) is a high-purity analytical reference standard with the molecular formula C18H18N2O7 and a molecular weight of 374.34 g/mol.
2-(2-(3,4,5-Trimethoxybenzoyl)hydrazine-1-carbonyl)benzoic acid (C18H18N2O7) contains a flavonoid core, 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
