Chemical Structure
Description
The occurrence of 1-[(4-Methylbenzene)sulfonyl]-1H-pyrrol-2-ol 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.
1-[(4-Methylbenzene)sulfonyl]-1H-pyrrol-2-ol (CAS 1881288-77-2) is a high-purity analytical reference standard with the molecular formula C11H11NO3S and a molecular weight of 237.27 g/mol.
The molecular framework of 1-[(4-Methylbenzene)sulfonyl]-1H-pyrrol-2-ol (C11H11NO3S) 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.
As a certified reference material (CRM), 1-[(4-Methylbenzene)sulfonyl]-1H-pyrrol-2-ol 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.
