Hexamethylenetetramine Specification

The Hexamethylenetetramine is an organic compound with the formula C6H12N4. The systematic name of this chemical is 1,3,5,7-tetraazatricyclo[3.3.1.13,7]decane. With the CAS registry number 100-97-0, it is also named as 1,3,5,7-tetraazaadamantane. The product's categories are Organics; Amination; Synthetic Organic Chemistry; Organic Chemicals. Besides, it is a white crystalline powder, which should be stored in a cool and ventilated place.

The Hexamethylenetetramine is used in the plastics indusrty, as a solid fuel and in some drugs. The term methenamine (an International Nonproprietary Name) is more common in its medicinal uses, and hexamine is more common in commercial uses. The primary use of Hexamethylenetetramine is in the manufacture of powdery or liquid preparations of phenolic resins and phenolic resin moulding compounds, where hexamine is added as a hardening component. These products are used as binders, e.g. in brake and clutch linings, abrasive products, non-woven textiles, formed parts produced by moulding processes, and fireproof materials. Hexamethylenetetramine is also used as an accelerator for rubber. It is used to some extent in medicine as an internal.
