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.
CATO supplies 3-(4-chloro-3-fluorobenzoyl)-4H,5H,6H-cyclopenta[b]thiophen-2-amine (CAS 1443981-54-1), a certified reference material (molecular formula C14H11ClFNOS, MW 295.76 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 3-(4-chloro-3-fluorobenzoyl)-4H,5H,6H-cyclopenta[b]thiophen-2-amine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 295.76 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.
As a certified reference material (CRM), 3-(4-chloro-3-fluorobenzoyl)-4H,5H,6H-cyclopenta[b]thiophen-2-amine 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.
