Frequently Asked Questions

What are the other names for EDDM?+
EDDM is the common abbreviation for (ethylenedioxy)dimethanol, CAS 3586-55-8. Chemical synonyms include 1,6-dihydroxy-2,5-dioxahexane, 1,2-bis(hydroxymethoxy)ethane, 2-(hydroxymethoxy)ethoxymethanol, ethylene glycol bis(hydroxymethyl ether), ethylene glycol bis(semiformal) and dimethylol glycol. All refer to the same substance.
What is the EINECS / EC number for EDDM?+
EDDM has EINECS / EC number 222-720-6 and CAS number 3586-55-8, with molecular formula C₄H₁₀O₄ and molecular weight 122.12 g/mol.
What is 'EGForm' in relation to EDDM?+
In the EU biocidal-products framework, EDDM is described as '(ethylenedioxy)dimethanol — reaction products of ethylene glycol with paraformaldehyde', abbreviated EGForm. It denotes the same active substance and is the designation used in regulatory listings for the in-situ formaldehyde-releasing chemistry.
Is EDDM the same as ethylene glycol hemiformal?+
Yes — 'ethylene glycol bis(semiformal)' and related hemiformal descriptors refer to the reaction product of ethylene glycol with formaldehyde/paraformaldehyde that is EDDM (CAS 3586-55-8). These are chemical descriptors of the same molecule.
Why do buyers see so many names for the same product?+
Chemical suppliers, regulatory registers and technical data sheets each use different naming conventions — IUPAC systematic names, common names, abbreviations and regional designations. Matching them to a single CAS number (3586-55-8) confirms you are specifying the same substance regardless of the name used.
