Dimethyleneglycol, also known as ethylene glycol or 1,2-ethanediol, is a colorless, viscous, and hygroscopic liquid with the chemical formula C2H6O2. It is an organic compound widely used as a solvent, antifreeze, and heat transfer medium in various industrial applications. Ethylene glycol is produced through the hydration of ethylene oxide, which is derived from the petrochemical industry. It has a sweet taste and a low freezing point, making it an effective coolant in automotive radiators and a common ingredient in de-icing solutions. Additionally, it is used in the manufacturing of polyester fibers, resins, and other chemicals. However, it is toxic if ingested and requires proper handling and disposal to prevent environmental and health risks.

Check Digit Verification of cas no

The CAS Registry Mumber 4407-89-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,0 and 7 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4407-89:
(6*4)+(5*4)+(4*0)+(3*7)+(2*8)+(1*9)=90
90 % 10 = 0
So 4407-89-0 is a valid CAS Registry Number.

Crosslinking of Gelatin with Formaldehyde; a 13C NMR Study

Albert, Klaus,Peters, Bernadette,Bayer, Ernst,Treiber, Ulrich,Zwilling, Michael

, p. 351 - 358 (2007/10/02)

The different species formed when gaseous formaldehyde is dissolved in aqueous medium are investigated by a 13C NMR flow-through technique and the spectra of commercial aqueous formaldehyde solutions containing methanol completely interpreted. 13CH2O was used to study the crosslinking reaction with gelatin which leads to methylene and oxymethylene bridges between gelatin-amino-groups.On ageing, hardened gelatin shows an increase in the number of methylene bridges. - Keywords: Aqueous Formalin Solution Compositions, Gelatin Cross-Linking, Gelatin Hardening, Static and Continuous Flow, 13C NMR

Carbon-13 NMR Study of Reaction of Aqueous Formaldehyde with Amine Salts: Evidences for Reductive Methylation by Intramolecular Hydride Transfer

Narasimhan, S.,Balakrishnan, M.,Kumar, A. S.,Venkatasubramanian, N.

, p. 568 - 570 (2007/10/02)

Reductive methylation of amine salts by aqueous formaldehyde under acidic conditions proceeds through the initial formation of hydroxymethylamine intermediates, followed by intramolecular hydride transfer. 13C NMR studies on this reaction and the mechanism are discussed.
