It forms high-order oligomers in aqueous solution and can form a 1:1 complex with Cu2+ through its hydroxyalkyl and tertiary amine groups. However, it contains a structurally similar trace impurity that lacks an alkanesulfonic acid side chain; the complex this impurity forms with Cu2+ has a very low Ka, so HEPPSO may interfere with copper speciation analysis in natural water bodies\u003csup\u003e[1][2]\u003c\/sup\u003e. It is supplied as a white to off-white solid (C9H20N2O5S, MW 268.33) at 99.95% purity.\u003c\/p\u003e\n\u003ch2\u003ePhysical \u0026amp; Chemical Properties\u003c\/h2\u003e\n\u003ctable class=\"bhp-spec-table\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eCAS Number\u003c\/th\u003e\n\u003ctd\u003e68399-78-0\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMolecular Formula\u003c\/th\u003e\n\u003ctd\u003eC9H20N2O5S\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMolecular Weight\u003c\/th\u003e\n\u003ctd\u003e268.33 g\/mol\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePurity\u003c\/th\u003e\n\u003ctd\u003e99.95%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eAppearance\u003c\/th\u003e\n\u003ctd\u003eSolid\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eColor\u003c\/th\u003e\n\u003ctd\u003eWhite to off-white\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSMILES\u003c\/th\u003e\n\u003ctd\u003eO=S(CC(O)CN1CCN(CCO)CC1)(O)=O\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSolubility\u003c\/th\u003e\n\u003ctd\u003eIn Vitro: H2O: 116.67 mg\/mL (434.80 mM; Requires sonication)\u003cbr\u003eDMSO: 100 mg\/mL (372.68 mM; Requires sonication and warming and heat to 60°C; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eStorage\u003c\/th\u003e\n\u003ctd\u003ePowder: -20°C, 3 years; 4°C, 2 years.
