Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3,4-Thiophenedicarboxylic Anhydride.
3,4-Thiophenedicarboxylic Anhydride (CAS 6007-85-8), molecular formula C6H2O3S and molecular weight 154.14 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, an aromatic ring system, 3,4-Thiophenedicarboxylic Anhydride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 154.14 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).
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), 3,4-Thiophenedicarboxylic Anhydride 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.
