Uses
Tris(hydroxymethyl)nitromethane, is used as an important raw material and intermediate used in organic Synthesis, pharmaceuticals, agrochemicals and dyestuff. It is used as a primary and secondary intermediate.
Preparation
Tris(hydroxymethyl)nitromethane is prepared by the condensation of nitromethane and formaldehyde under basic conditions.
Application
Tris(hydroxymethyl)nitromethane is a bactericide and slimicide for use in cooling fluids, paper and pulp industry; as a curing agent for certain adhesives; viscositycontrolling agent in cosmetics.To inhibit bacterial growth in circulating industrial water systems, cutting oils, nonprotein glues and sizings.
General Description
Tris(hydroxymethyl)nitromethane undergoes crosslinking with hexamethylene diisocyanate to form monolithic energetic gels. It is an effective hardener for variety of tannin-based adhesives.
Purification Methods
Crystallise it from CHCl3/ethyl acetate or ethyl acetate/*benzene. It is an acid and a 0.1M solution in H2O has pH 4.5. IRRITANT. [Beilstein 1 H 520.]
Check Digit Verification of cas no
The CAS Registry Mumber 126-11-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,2 and 6 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 126-11:
(5*1)+(4*2)+(3*6)+(2*1)+(1*1)=34
34 % 10 = 4
So 126-11-4 is a valid CAS Registry Number.

Formation and Out-of-Equilibrium, High/Low State Switching of a Nitroaldol Dynamer in Neutral Aqueous Media
Elofsson, Ulla,Karalius, Antanas,Kravchenko, Oleksandr,Ramstr?m, Olof,Szabó, Zoltán,Yan, Mingdi,Zhang, Yang
, p. 3434 - 3438 (2020)
The nitroaldol reaction is demonstrated as an efficient dynamic covalent reaction in phosphate buffers at neutral pH. Rapid equilibration was recorded with pyridine-based aldehydes, and dynamic oligomerization could be achieved, leading to nitroaldol dynamers of up to 17 repeating units. The dynamers were applied in a coherent stimuli-responsive molecular system in which larger dynamers transiently existed out-of-equilibrium in a neutral aqueous system rich in formaldehyde, controlled by nitromethane.
IS 1,3-DIHYDROXYPROPANENITRONIC ACID REALLY STABLE?
Eremenko, L. T.,Oreshko, G. V.,Lagodzinskaya, G. V.,Zabrodin, V. A.
, p. 555 - 557 (1990)
The condensation of nitromethane with paraformaldehyde in the presence of catalytic amounts of KF and tetra-n-butylammonium bromide in a medium of isopropanol does not afford stable 1,3-dihydroxypropanenitronic acid.In the neutralization of 2-nitro-1,3-propanediol sodium salt by anhydrous CF3COOH, 2-nitro-1,3-propanediol and 2-nitro-1-propen-3-ol were identified.
PROCESS FOR THE PREPARATION OF NITROALCOHOLS

Paragraph 0018, (2013/09/26)
A process of preparing a nitroalcohol, e.g., 2-nitro-2-methyl-1-propane, from a nitropolyol, e.g., 2-nitro-2 -methyl-1,3-propanediol, the process comprising the step of contacting under hydrogenation conditions the nitropolyol with hydrogen, a hydrogenation catalyst and, optionally, a chelating agent.
