Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 3-(2-Nitro-4-(trifluoromethyl)phenoxy)thiophene-2-carboxylic acid (CAS 252026-58-7), a certified reference material (molecular formula C12H6F3NO5S, MW 333.24 g/mol) for analytical method development and quality control.
Structurally, 3-(2-Nitro-4-(trifluoromethyl)phenoxy)thiophene-2-carboxylic acid (C12H6F3NO5S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 333.24 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), 3-(2-Nitro-4-(trifluoromethyl)phenoxy)thiophene-2-carboxylic 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.
