Description
3-Mercapto-1-propanesulfonic acid sodium is a sodium salt of a mercaptoalkanesulfonic acid supplied for laboratory chemical and biochemical applications. It is registered under CAS number 17636-10-1 with the empirical formula C₃H₇O₃S₂Na and a molar mass of 178,21 g/mol. A flash point of 71 °C is reported, supporting informed handling decisions during weighing, dissolution, and transfer steps in controlled laboratory environments. The product is Dual sulfur functionality—thiol and sulfonate—makes the molecule relevant where water-compatible thiol reagents or sulfonated linkers are required. This material is offered by manufacturer Carl ROTH with the identity parameters needed for catalogue traceability and internal quality records. Laboratories can incorporate the salt into surface chemistry, electrochemistry adjunct work, or synthetic sequences that benefit from a short-chain mercaptosulfonate. The defined molar mass simplifies stoichiometric calculations, while the substantial pack size supports both pilot batches and routine replenishment. Clear CAS and formula labelling help maintain consistent naming across purchasing, safety files, and electronic notebooks throughout a project lifecycle.

Questions about 3-Mercapto-1-propanesulfonic acid sodium, salt, 250 g
What is this article?
3-Mercapto-1-propanesulfonic acid sodium, salt, 250 g is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Inorganic salts, inside Inorganic chemicals, in Lab chemicals.
An inorganic salt is an ionic solid, a chloride, a sulfate, a nitrate, a phosphate. The degree of hydration changes the mass that contains one mole of the ion. Analytical grade limits the foreign ions. A hydrate and the anhydrous salt are not interchangeable by weight.
An inorganic chemical is a salt, an acid or base in solid form, a metal, an oxide, or an element. The waters of hydration are part of the formula: a hydrate and an anhydrous salt are different masses for the same ion. Trace metals matter when the salt will be used in analysis. Nanomaterials add particle size to the specification. Look the substance up on PubChem. Hazard classes are on ECHA, under the CLP Regulation and REACH. Transport of the dangerous ones is explained by the UNECE.
