Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 267.09 g/mol gives N-(4-Iodothiophen-2-yl)acetamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
N-(4-Iodothiophen-2-yl)acetamide (CAS 1935147-55-9) is a high-purity analytical reference standard with the molecular formula C6H6INOS and a molecular weight of 267.09 g/mol.
Owing to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system, N-(4-Iodothiophen-2-yl)acetamide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 267.09 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), N-(4-Iodothiophen-2-yl)acetamide 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.
