Chemical Structure
Description
As a certified reference material (CRM), 4-(5-oxopyrrolidin-2-yl)benzene-1-sulfonyl chloride 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.
4-(5-oxopyrrolidin-2-yl)benzene-1-sulfonyl chloride (CAS 1909313-88-7), molecular formula C10H10ClNO3S and molecular weight 259.71 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-(5-oxopyrrolidin-2-yl)benzene-1-sulfonyl chloride (C10H10ClNO3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
