Compared with other compounds in its class, the molecular weight of 304.34 g/mol gives 2,8-Thianthrenedicarboxylic Acid(contain ~5% 2,7-isomer) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2,8-Thianthrenedicarboxylic Acid(contain ~5% 2,7-isomer) (CAS 154341-97-6), molecular formula C14H8O4S2 and molecular weight 304.34 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, 2,8-Thianthrenedicarboxylic Acid(contain ~5% 2,7-isomer) is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 304.34 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2,8-Thianthrenedicarboxylic Acid(contain ~5% 2,7-isomer) 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.
