(2S,3S)-2,3-dihydroxybutanal, also known as erythrulose, is a chiral aldehyde with the molecular formula C4H8O3. It is a four-carbon sugar alcohol derived from the reduction of the ketose sugar erythrose. This optically active compound is characterized by its two hydroxyl groups (-OH) at the 2nd and 3rd carbon positions, and it exists in the S configuration at both chiral centers. Erythrulose is used in various applications, including as a tanning agent in cosmetic products, a reducing sugar in food and beverages, and a building block in the synthesis of other organic compounds. Its unique properties make it valuable in the fields of chemistry, biology, and materials science.

5144-77-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5144-77-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,4 and 4 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 5144-77:
(6*5)+(5*1)+(4*4)+(3*4)+(2*7)+(1*7)=84
84 % 10 = 4
So 5144-77-4 is a valid CAS Registry Number.

SYNTHESIS AND N.M.R.-SPECTRAL ANALYSIS OF UNENRICHED AND -ENRICHED 5-DEOXYPENTOSES AND 5-O-METHYLPENTOSES

Snyder. Joseph R.,Serianni, Anthony S.

, p. 169 - 188 (2007/10/02)

Chemical methods are described for preparing unenriched and -enriched 5-deoxy- and 5-O-methyl-pentoses in the D or L configuration.The 1H-n.m.r.-spectra of these compounds have been interpreted, and the 13C n.m.r. spectra assigned with the aid of 2-D 13C-1H chemical-shift correlation spectroscopy.Tautomeric forms (furanoses, hydrate, and aldehyde) in solution in 2H2O have been quantified with the aid of -enriched derivatives.Spectra of 5-deoxypentoses, and methyl pentofuranosides have been compared, in order to assess the effect of 5-C-deoxygenation and 5-O-methylation on chemical shifts and coupling constants (1H-1H, 13C-1H, and 13C-13C) and on the pentofuranose conformations.
