Description
As a certified reference material (CRM), trans-Butane-1,2,3,4-tetracarboxylic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
trans-Butane-1,2,3,4-tetracarboxylic acid (CAS 4534-68-3) is a high-purity analytical reference standard with the molecular formula C8H10O8 and a molecular weight of 234.16 g/mol.
The molecular framework of trans-Butane-1,2,3,4-tetracarboxylic 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.
