131-69-1 Usage
Uses
antibacterial
Brand name
Talsigel (Bristol-Myers Squibb); Thalamyd
(Schering) [Name previously used: Phthalylsulphacetamide.].
Purification Methods
It is prepared by hydrolysis of N-acetamidosulfophenylpthalimide by boiling for 3hours in 15% aqueous KOH followed by treatment with Norit, filtration and acidification with AcOH. Crystallise the phthalamide from hot H2O or EtOH [Jain et al. J Indian Chem Soc 24 174 1947]. Itis antibacterial.[Beilstein 14 III 2073.]
Check Digit Verification of cas no
The CAS Registry Mumber 131-69-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,3 and 1 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 131-69:
(5*1)+(4*3)+(3*1)+(2*6)+(1*9)=41
41 % 10 = 1
So 131-69-1 is a valid CAS Registry Number.

Solid-solid reaction between sulfacetamide and phthalic anhydride
Weng,Parrott
, p. 1059 - 1063 (1984)
Thermal and kinetic data for the solid-state addition reaction of sulfacetamide and phthalic anhydride are presented. A compaction method was used so that the influence of some pharmaceutical parameters (compressional pressure, particle size, concentration, and temperature) on the reaction kinetics could be observed.
