Chemical Structure
Description
The occurrence of 2-Hydroxybutane-1,2,4-tricarboxylic acid is closely related to a carbohydrate-derived structure in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2-Hydroxybutane-1,2,4-tricarboxylic acid (CAS 3562-74-1), a certified reference material (molecular formula C7H7O7, MW 203.13 g/mol) for analytical method development and quality control.
Structurally, 2-Hydroxybutane-1,2,4-tricarboxylic acid (C7H7O7) contains a carbohydrate-derived structure. The molecule exhibits a degree of unsaturation (DBE) of 4.5, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 203.13 g/mol, it falls into the medium-molecular-weight range. 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.
