Dodecyl benzene sulfonic acid Specification

The Dodecyl benzene sulfonic acid, with the CAS registry number 27176-87-0, is also known as Laurylbenzenesulfonic acid. It belongs to the product categories of Organic Conductors and Photovoltaics: OFET and OPV Materials;Polymer Additives.This chemical's molecular formula is C18H30O3S and molecular weight is 326.49.Its EINECS number is 248-289-4. What's more,Its systematic name is Dodecyl benzene sulfonic acid.It is  a colorless liquid,Stable,Hygroscopic,Incompatible with bases,oxidizing agents,metals,and is soluble in water alcohols, glycol ethers, glycols, esters, ketones, aromatic and aliphatic hydrocarbons.The Dodecyl benzene sulfonic acid is corrosive. When heated to decomposition or on contact with strong acids produces highly toxic fumes of oxides of sulfur. The toxicity and hazards of individual alkylbenzene sulfonic acids must be assessed individually.
