Polyhexamethylene guanidine (PHMG) is a guanidine derivative that is used as a biocidal disinfectant, often in the form of its salt polyhexamethylene guanidine phosphate (PHMG-P). Studies have shown that PHMG in solution has fungicidal as well as bactericidal activity against both Gram-positive and Gram-negative bacteria . [ 2 ]
The main cause of the lung diseases was the chemicals PHMG, methylchloroisothiazolinone (CMIT), methylisothiazolinone (MIT) and oligo(2-(2-ethoxy)-ethoxyethyl)guanidinium-chloride (PGH). [3] Experiments by the South Korean government found pulmonary toxicity of PHMG and PGH when inhaled as a vapor.
Chemical nomenclature, replete as it is with compounds with very complex names, is a repository for some names that may be considered unusual. A browse through the Physical Constants of Organic Compounds in the CRC Handbook of Chemistry and Physics (a fundamental resource) will reveal not just the whimsical work of chemists, but the sometimes peculiar compound names that occur as the ...
Polyhexanide (polyhexamethylene biguanide, PHMB) is a polymer used as a disinfectant and antiseptic.In dermatological use, [4] it is spelled polihexanide and sold under various brand names. [5]
Phenylmagnesium bromide is a strong nucleophile as well as a strong base.It can abstract even mildly acidic protons, thus the substrate must be protected where necessary. It often adds to carbonyls, such as ketones, aldehyde

The main structure of chemical names according to IUPAC nomenclature. IUPAC nomenclature is a set of recommendations for naming chemical compounds and for describing chemistry and biochemistry in general. The International Union of Pure and Applied Chemistry (IUPAC) is the international authority on chemical nomenclature and terminology.
