Chemical Structure

Lithium4-vinylbenzenesulfonate CAS 4551-88-6 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Lithium4-vinylbenzenesulfonate.

Lithium4-vinylbenzenesulfonate (CAS 4551-88-6) is a high-purity analytical reference standard with the molecular formula C8H7O3SLi and a molecular weight of 190.14 g/mol.

Lithium4-vinylbenzenesulfonate (C8H7O3SLi) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), Lithium4-vinylbenzenesulfonate 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.
