Recrystallise the hydrogensulfate (1:1) from EtOH/Et2O (hygroscopic leaflets). The Sulfate (2:1) [5466-22-8] crystallises as flat prisms from H2O/EtOH with m 166o(dec). [Stephen J Chem Soc 871 1931, Anslow & King J Chem Soc 2465 1929, Beilstein 4 III 1120.]
Check Digit Verification of cas no
The CAS Registry Mumber 151-63-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,5 and 1 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 151-63:
(5*1)+(4*5)+(3*1)+(2*6)+(1*3)=43
43 % 10 = 3
So 151-63-3 is a valid CAS Registry Number.

Synthesis of [3-13C]-, [4-13C]- and [11- 13C]-porphobilinogen

[4-13C]-porphobilinogen 1a, [3-13C]-porphobilinogen 1b and [11-13C]-porphobilinogen 1c are prepared from [1- 13C]-3-(tetrahydropyran-20-yloxy)-propionaldehyde 2a, methyl [4- 13C]-4-nitrobutyrate 3b and [1-13C]-isocyanoacetonitrile 5c, respectively. The building blocks 2, 3 and 5 can be prepared efficiently in any isotopomeric form. Via base-catalyzed condensation of these building blocks porphobilinogen can be enriched with 13C and 15N stable isotopes at any position and combination of positions. Copyright
