Chemical Structure
Description
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, Sodium Gualenate Impurity 1 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 268.33 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO supplies Sodium Gualenate Impurity 1 (CAS CATO-C4X-29271), a pharmacopoeial impurity reference standard (molecular formula C13H16O4S, MW 268.33 g/mol) used for the identification and quantification of trace impurities in APIs.
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
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.
