1-Hexadecanesulfonic acid sodium salt (CH3(CH2)15SO3Na) is a high-purity analytical reagent used mainly as an ion-pairing reagent in reversed-phase HPLC. Its long C16 alkyl chain and anionic sulfonate group let it pair with basic and cationic analytes, increasing and controlling their retention for chromatographic separation. This chemical has a CAS number of 15015-81-3, a molecular formula of CH3(CH2)15SO3Na, and a molecular weight of 328.49 g/mol. It is stable at ambient storage conditions and carries a signal word of "Warning" for safety classification. Molekula supplies 1-Hexadecanesulfonic acid sodium salt from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
