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.
Matching a specification to EDDM?
Whatever name your specification uses, Vasudev Chemo Pharma supplies the same substance — EDDM (CAS 3586-55-8) — in 90%, 92% and 95% grades with batch COA and global export from Gujarat, India.
