Sodium Pentanesulfonate CAS 22767-49-3

1. Sodium pentanesulfonate CAS 22767-49-3 is primarily used as an ion-pairing reagent in reversed-phase high-performance liquid chromatography (RP-HPLC) for the analysis of peptides, proteins, and other small organic molecules .
2. Sodium pentanesulfonate serves as an anionic surfactant and surface-active agent in research applications, including studies on drug release from water-in-oil-in-water multiple emulsions .
3. Sodium pentanesulfonate is employed in micellar electrokinetic chromatography and analytical studies for the separation and detection of pharmaceutical products and metabolites .
4. Researchers utilize Sodium pentanesulfonate in sonochemical and spin-trapping techniques with electron paramagnetic resonance spectroscopy (EPR) for investigating ion-pairing mechanisms .

1. Sodium pentanesulfonate CAS 22767-49-3 must be stored in a tightly sealed container in a cool, dry, and well-ventilated environment, protected from light and moisture .
2. Sodium pentanesulfonate is hygroscopic and should be kept away from strong oxidizing agents, as it may pose a combustion risk under high-temperature conditions .
3. Personnel must wear chemical-resistant gloves, safety goggles with side-shields (type N95 or equivalent), and protective clothing when handling this substance to prevent skin and eye irritation .
4. Use adequate ventilation to avoid dust formation and inhalation; wash thoroughly after handling .

1. Isolate the spill area, ensure adequate ventilation, and wear full personal protective equipment including chemical-resistant gloves, safety goggles, and a suitable dust respirator when Sodium pentanesulfonate is released .
2. Collect Sodium pentanesulfonate by sweeping or vacuuming without creating dust using non-sparking tools, and place into suitable closed containers for disposal .
3. Avoid creating dust clouds during cleanup to prevent respiratory exposure; decontaminate surfaces using appropriate methods .
4. Prevent the product from entering drains or water courses, and dispose of collected material as hazardous waste according to local, state, and federal environmental regulations .

1. Sodium pentanesulfonate CAS 22767-49-3 is not classified as highly flammable (NFPA Fire rating of 1), but may decompose under fire conditions, emitting toxic fumes including carbon oxides, sulfur oxides, and sodium oxides .
2. Use water spray, alcohol-resistant foam, dry chemical powder, or carbon dioxide to extinguish fires involving the product; do NOT use a direct water jet as Sodium pentanesulfonate may scatter burning material .
3. Firefighters should wear self-contained breathing apparatus in pressure-demand, MSHA/NIOSH approved, and full protective gear when handling burning Sodium pentanesulfonate .
4. During combustion, may emit irritant and toxic fumes; move containers from the fire area if safe to do so, cool exposed containers with water spray from a protected location, and contain fire runoff to prevent environmental contamination .
