2972-19-2 Usage
General Description
1,2,3-Propanetriol, 2-(hydroxymethyl)-, also known as trimethylolpropane, is a colorless, odorless, and stable chemical compound commonly used as a building block in the production of polyurethanes and synthetic lubricants. It is a trihydric alcohol with three hydroxyl groups, and its versatile nature allows it to be used in a wide range of applications, including coatings, adhesives, automotive parts, and pharmaceuticals. Trimethylolpropane is considered relatively safe and non-toxic, making it a preferred choice for various industrial purposes. Additionally, it is known for its high stability and resistance to heat, making it an ideal component in the manufacturing of durable and long-lasting materials.
Check Digit Verification of cas no
The CAS Registry Mumber 2972-19-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,7 and 2 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2972-19:
(6*2)+(5*9)+(4*7)+(3*2)+(2*1)+(1*9)=102
102 % 10 = 2
So 2972-19-2 is a valid CAS Registry Number.

Formose reactions, XXVIII. Selective formation of 2,4-bis(hydroxymethyl)-3-pentulose in N,N-dimethylformamide-water mixed solvent
Shigemasa,Ueda,Saimoto
, p. 389 - 394 (2007/10/02)
Dihydroxyacetone, DL-glycero-tetrulose, and 2,4-bis(hydroxymethyl)-3-pentulose (2,4-BH-3-P) were favorably formed in a formose reaction by choosing a suitable ratio of water to N,N-dimethylformamide used as solvent or a suitable [thiamine.HCl]/[HCHO] ratio. The formose reaction was strongly affected by the concentration of formaldehyde in the water layer. Under the reaction conditions studied, thiamine decomposed rapidly. 2,4-BH-3-P was isolated from the reaction mixture and characterized by MS, IR, and NMR techniques. A pathway for the formation of 2,4-BH-3-P was also proposed.
