Isopropyl 4-DoDecyl Benzene sulfphonate

Isopropyl 4-Dodecyl Benzene sulfphonate is a branched ester derivative featuring a dodecyl-substituted benzene ring linked to a sulfonate group via an isopropyl ester linkage. The molecule comprises a 12-carbon alkyl chain at the para-position of the benzene core, conjugated to a sulfonic acid moiety esterified with isopropanol. Structurally, it represents a synthetic byproduct arising during the esterification of dodecylbenzene sulfonic acid with isopropyl alcohol, commonly encountered in the production of surfactant-based APIs. This compound serves as an HPLC reference standard for quantifying process-related impurities in dodecylbenzene sulfonate derivatives.
