Description
As a certified reference material (CRM), N-(4-oxotetrahydrothiophen-3-yl)benzamide 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.
N-(4-oxotetrahydrothiophen-3-yl)benzamide (CAS 62578-77-2), molecular formula C11H11NO2S and molecular weight 221.28 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N-(4-oxotetrahydrothiophen-3-yl)benzamide (C11H11NO2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
