Description
Polyhexamethylene biguanide hydrochloride is a polymeric biguanide salt identified by CAS number 32289-58-0 and represented by the empirical formula (C₈H₁₇N₅)ₙ(HCl)ₓ. The material has a density of 1,04 g/cm³. It belongs to the chemicals and biochemicals assortment and is available from manufacturer Carl ROTH, with transport classification under UN number 2810. The polymeric structure combines repeating hexamethylene and biguanide units in hydrochloride form, giving a defined chemical identity for research documentation and inventory control. quantity is practical for laboratories that require moderate amounts for method development, comparative studies, or routine experimental series. Density information assists when preparing solutions or verifying received material against specification. As with other specialty polymers in this category, appropriate personal protective equipment and chemical hygiene measures should be observed during weighing and dissolution. This article supports research groups working with cationic polymeric biguanides in chemical and biochemical contexts.
This article is part of Inorganic salts, in Inorganic chemicals.

Questions about Polyhexamethylene biguanide hydrochlorid, e, Density (D) 1,04 g/cm³
What is this article?
Polyhexamethylene biguanide hydrochlorid, e, Density (D) 1,04 g/cm³ 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.
