Sodium 5,6,7,8-tetrahydronaphthalene-2-sulfinate CAS 1504174-30-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Sodium 5,6,7,8-tetrahydronaphthalene-2-sulfinate.

Sodium 5,6,7,8-tetrahydronaphthalene-2-sulfinate (CAS 1504174-30-4), molecular formula C10H11O2SNa and molecular weight 218.25 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Sodium 5,6,7,8-tetrahydronaphthalene-2-sulfinate (C10H11O2SNa) 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 218.25 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

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.
