Hexamine Hydrochloride

Updated: 2026-09-15

Overview

Hexamine Hydrochloride, also known as Methenamine hydrochloride, is a white crystalline powder with a molecular formula of C6H13ClN4. It is derived from the reaction of hexamethylenetetramine with hydrochloric acid. This compound is widely used in various industrial applications due to its stability and reactivity. Hexamine Hydrochloride is particularly valued in organic synthesis and pharmaceuticals, where it serves as a precursor or intermediate. Its ability to release formaldehyde under specific conditions makes it useful in cross-linking reactions and as a disinfectant.

Physical and Chemical Properties

Hexamine Hydrochloride is characterized by its white crystalline appearance and solubility in water. It has a density of 1.33 g/cm³ and decomposes at temperatures between 280-285°C. The compound is non-hygroscopic, meaning it does not absorb moisture from the air, which contributes to its stability during storage. Key chemical properties include its ability to release formaldehyde when heated, which is exploited in various industrial processes. It is slightly soluble in alcohol but readily dissolves in water, making it versatile for aqueous solutions and formulations.

Main Applications

Hexamine Hydrochloride finds extensive use in organic synthesis, particularly as a building block for more complex compounds. In the pharmaceutical industry, it is utilized as an intermediate in the production of certain drugs and disinfectants. Another significant application is as a corrosion inhibitor, especially in boiler water treatment and metal protection. The rubber industry also employs Hexamine Hydrochloride as a vulcanization accelerator, enhancing the properties of rubber products.

Safety and Storage

Proper handling of Hexamine Hydrochloride is essential to ensure safety. It should be stored in a cool, dry, and well-ventilated area, away from moisture and incompatible substances such as strong oxidizers. Personal protective equipment, including gloves and goggles, should be worn when handling the compound. In case of exposure, immediate measures such as rinsing with water or seeking medical attention may be necessary. Safety Data Sheets (SDS) should always be consulted for detailed hazard information and first-aid procedures.

B2B Procurement Guide

When procuring Hexamine Hydrochloride, businesses should prioritize suppliers who provide a Certificate of Analysis (COA) to verify purity and quality. Packaging options, such as sealed bags or drums, should be chosen based on storage and handling requirements. Price negotiation should consider factors like order volume, purity specifications, and delivery terms. It is advisable to establish long-term relationships with reliable suppliers to ensure consistent quality and availability.
