Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 298.16 g/mol gives Benzenepentacarboxylic Acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Benzenepentacarboxylic Acid (CAS 1585-40-6) is a high-purity analytical reference standard with the molecular formula C11H6O10 and a molecular weight of 298.16 g/mol.
Owing to a carbohydrate-derived structure, Benzenepentacarboxylic Acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 298.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), Benzenepentacarboxylic 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.
