Import Tips & Compliance
• Include esterification verification and molecular formula C8H10O3S in technical data sheet
• Stability data required; ethyl esters can hydrolyze during transport affecting purity claims
• Distinguish from petroleum sulfonic acids (2710) via parent hydrocarbon identification
