Chemical Structure
Description
The occurrence of 1,2,3,4-butanetetracarboxylic acid is closely related to a carbohydrate-derived structure in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 1,2,3,4-butanetetracarboxylic acid (CAS 1703-58-8), a certified reference material (molecular formula C8H10O8, MW 234.16 g/mol) for analytical method development and quality control.
The molecular framework of 1,2,3,4-butanetetracarboxylic acid (C8H10O8) is characterized by a carbohydrate-derived structure. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
