n-(4-Hydroxyphenyl)-5-methylthiophene-2-sulfonamide CAS 1042647-34-6

Description

The occurrence of n-(4-Hydroxyphenyl)-5-methylthiophene-2-sulfonamide is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

n-(4-Hydroxyphenyl)-5-methylthiophene-2-sulfonamide (CAS 1042647-34-6), molecular formula C11H11NO3S2 and molecular weight 269.34 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of n-(4-Hydroxyphenyl)-5-methylthiophene-2-sulfonamide (C11H11NO3S2) 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. 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), n-(4-Hydroxyphenyl)-5-methylthiophene-2-sulfonamide 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.
