Product Description

Detailed information about the product

Product Overview

1-Butane Sulphonic Acid Sodium Salt Anhydrous 99% AR/HPLC (CAS No. 2386-54-1) is anhydrous sodium butane-1-sulfonate, an alkali-metal alkylsulfonate containing a four-carbon hydrophobic chain and a permanently anionic sulfonate group. In reversed-phase ion-pair chromatography, the sulfonate functions as a counterion for positively charged analytes and modifies their effective interaction with the stationary phase, thereby influencing retention, selectivity and peak behaviour. The anhydrous identity is important when calculating reagent quantities for molar mobile-phase preparation.

The AR/HPLC grade is intended for analytical reagent preparation and use as an anionic ion-pairing additive in high-performance liquid chromatography. Its grade territory requires suitability for mobile-phase formulation with controlled chromatographic background and reagent cleanliness.

Typical Applications

  • Anionic ion-pair reagent in reversed-phase HPLC for protonated amines and other cationic analytes.
  • Mobile-phase additive used to improve retention, selectivity and peak shape for polar basic compounds.
  • Preparation of ion-pair chromatographic mobile phases for analytical method development and routine quality-control procedures.
  • Component of mixed ion-pair systems used in selected chromatographic speciation methods for selenium compounds.
  • Use in selected HPLC–element-specific detection procedures where sodium 1-butanesulfonate is specified.
  • General analytical reagent for studies involving alkylsulfonate counterions and ion-association behaviour.

Common Synonyms

  • Sodium 1-Butanesulfonate
  • Sodium Butane-1-Sulfonate
  • 1-Butanesulfonic Acid Sodium Salt
  • 1-Butanesulphonic Acid Sodium Salt
  • Sodium Butylsulfonate
  • Sodium n-Butylsulfonate

Storage Conditions

Store in a tightly closed container under dry conditions and protect from moisture and analytical contamination. Minimise exposure to humid air to preserve the anhydrous form and reduce variability during gravimetric preparation of chromatographic mobile phases.
