Chemical Structure

Sodium 4-vinylbenzenesulfinate CAS 60081-73-4 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 Sodium 4-vinylbenzenesulfinate.

Sodium 4-vinylbenzenesulfinate (CAS 60081-73-4) is a high-purity analytical reference standard with the molecular formula C8H7NaO2S and a molecular weight of 190.19 g/mol.

Structurally, Sodium 4-vinylbenzenesulfinate (C8H7NaO2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.5, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 190.19 g/mol, it falls into the medium-molecular-weight range. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
