Chemical Structure

But-3-ene-1,2,3-tricarboxylic acid CAS 26326-05-6 chemical structure

Description

As a certified reference material (CRM), But-3-ene-1,2,3-tricarboxylic 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.

But-3-ene-1,2,3-tricarboxylic acid (CAS 26326-05-6) is a high-purity analytical reference standard with the molecular formula C7H8O6 and a molecular weight of 188.13 g/mol.

The molecular framework of But-3-ene-1,2,3-tricarboxylic acid (C7H8O6) 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.
