(Z)-2-acetoxy-5-nitro-2,5-dihydrofurfural diacetate is a complex organic chemical compound with the molecular formula C9H11NO8. It is a derivative of furfural, a heterocyclic compound derived from the dehydration of carbohydrates. This specific compound features a furan ring with a nitro group at the 5-position, an acetoxy group at the 2-position, and two acetate groups attached to the hydroxyl groups. It is synthesized through a series of chemical reactions, including the acetylation of 5-nitro-2-furaldehyde and subsequent reduction to form the dihydro derivative. (Z)-2-acetoxy-5-nitro-2,5-dihydrofurfural diacetate is of interest in the field of organic chemistry, potentially for its reactivity or as a precursor to other complex molecules. It is important to note that due to its nitro and acetoxy groups, it should be handled with care, as it may be sensitive to heat and friction, and could potentially be explosive.

Check Digit Verification of cas no

The CAS Registry Mumber 75631-82-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,6,3 and 1 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 75631-82:
(7*7)+(6*5)+(5*6)+(4*3)+(3*1)+(2*8)+(1*2)=142
142 % 10 = 2
So 75631-82-2 is a valid CAS Registry Number.

Nitronium Acetate Adducts of Furan Derivatives

Balina, Gisela,Kesler, Patricia,Petre, Janet,Pham, Dung,Vollmar, Arnulf

, p. 3811 - 3818 (2007/10/02)

An improved procedure for the isolation of the main addition products of the reaction between nitronium acetate and furfural diacetate or methyl 2-furoate is described.The kinetics of the deacetylation of the diastereomeric 1,4-adducts in buffer solutions revealed a substantial primary hydrogen isotope effect.Mild acid-induced alcoholysis transformed the adducts into 2,5-dialkoxy-2,5-dihydrofurans.The reaction chemistry of the furan adducts is compared with the solvolytic pathways reported for ipso nitronium acetate adducts formed from alkylbenzenes.

MOLECULAR AND CRYSTALLINE STRUCTURE OF FURFURAL DIACETATE NITRATION INTERMEDIATE

Mishnev, A. F.,Bleidelis, J. J.,Venters, K. K.

, p. 1817 - 1820 (2007/10/02)

X-ray crystallography established the structure of the acetyl nitrate adduct to furfural diacetate (H.Gilman and G.F.Wright (1930)) as trans-2-acetoxy-5-nitro-2,5-dihydro-2-furfural diacetate (1a).The furanoid ring is essentially planar, its geometry being similar to that of 2,5-dihydrofuran molecule, except for the interatomic distance C(3)-C(4) which is shorter than the corresponding length of double C-C bond in alkenes.The C(5)-N 1.52 Angstroem bond significantly exceeds the standard C-N bond lengths in nitroalkanes and nitrobenzene.
