1315-04-4 Usage
Chemical Properties
orange powder
Physical properties
Orange-yellow or reddish amorphous powder; density 4.12 g/cm3; decomposes at 75°C; insoluble in water and alcohol; soluble in hydrochloric acid, caustic alkalies and ammonium hydrosulfide.
Uses
As pigment; vulcanizing and coloring rubber; manufacture of matches and fireworks.
Preparation
The compound is made commercially by converting antimony trisulfide to tetrathioantimonate by boiling with sulfur in caustic soda solution:4 Sb2S3 + 8 S +18 NaOH → 5 Na3SbS4 + 3 NaSbO3 + 9 H2OThe sparingly soluble sodium antimonate is filtered out of the solution. The yellow-orange antimony pentasulfide precipitates out on treatment with hydrochloric acid.2 Na3SbS4 + 6 HCl → Sb2S5 + 6 NaCl + 3 H2SIt may also be prepared by the reaction of antimony pentachloride in HCl with hydrogen sulfide and removing any free sulfur by extraction with carbon disulfide:2 SbCl5 + 5 H2S → Sb2S5 + 10 HCl.
Hazard
Flammable, dangerous fire risk near oxi-
dizing materials.
Safety Profile
Moderately toxic by
intraperitoneal route. See also ANTIMONY
COMPOUNDS and SULFIDES.
Flammable when exposed to heat or by
chemical reaction with powerful oxidtzers.
Use water to fight fire. Moderately explosive
when shocked or by spontaneous chemical
reaction in contact with powerful oxidtzers.
When heated to decomposition or on
contact with acid or acid fumes it emits
highly toxic fumes of oxides of sulfur and
antimony. Incompatible with water or steam
to produce toxic and flammable vapors and
with oxidizers, e.g., Ag(ClO3)2, HClO3,
ClO2, Mg(ClO3)2, TlO,Zn(ClO3)2.
Check Digit Verification of cas no
The CAS Registry Mumber 1315-04-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,1 and 5 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1315-04:
(6*1)+(5*3)+(4*1)+(3*5)+(2*0)+(1*4)=44
44 % 10 = 4
So 1315-04-4 is a valid CAS Registry Number.

Elaborated 1H NMR study for the ligitional behavior of two thiosemicarbazide derivatives towards some heavy metals (Sn(II), Sb(III), Pb(II) and Bi(III)), thermal, antibacterial and antifungal studies

A new series of heavy metal complexes are prepared. Sn(II), Sb(III), Pb(II) and Bi(III) are the metal ions used in complexation with two thiosemicarbazide ligands. The IR and 1H NMR spectra of the free ligands display their presence in thiole-thione forms coincide with each other. The IR spectra of the complexes support the presence of 2:2 molar ratio (M:HL) with HL1 ligand and 1:1 beside 1:2 with HL2. The ligand coordinates as bi molecules in some complexes and displays two tautomer forms at the same complex molecule 1H NMR spectra of Sn(II) and Sb(III) complexes were done and comes coincide with IR data. The electronic spectral analysis displays a lower shift appearance in n → π* charge transfer band in most isolated complexes. As well as, a new band is shinned in visible region with Sb(III), Bi(III) complexes and Sn(II)-HL2. This band is pointed to its use in spectrophotometric analysis for these metal ions. The TG analysis for all isolated compounds was briefly discussed. The molecular modeling parameters support the stability of thiole form of the free ligands in comparing with their thiones by a small difference. The antibacterial and antifungal activities were studied against some organisms and reveal the priority of most investigated complexes.
