Definition
ChEBI: A dithiocarbamate salt that is the zinc salt of dimethyldithiocarbamic acid. It is a broad-spectrum fungicide and bird and animal repellent that is also used to accelerate the vulcanisation of rubber.
Air & Water Reactions
Thio and dithiocarbamates slowly decompose in aqueous solution to form carbon disulfide and methylamine or other amines. Such decompositions are accelerated by acids. Insoluble in water.
Reactivity Profile
Zinc bis dimethyldithiocarbamate is a dithiocarbamate. Flammable gases are generated by the combination of thiocarbamates and dithiocarbamates with aldehydes, nitrides, and hydrides. Thiocarbamates and dithiocarbamates are incompatible with acids, peroxides, and acid halides. Zinc bis dimethyldithiocarbamate is corrosive to iron and copper. Zinc bis dimethyldithiocarbamate is incompatible with strong oxidizing agents and acids. Zinc bis dimethyldithiocarbamate is also incompatible with mercury.
Hazard
Strong irritant to eyes and mucous membranes.
Fire Hazard
Zinc bis dimethyldithiocarbamate is combustible. Zinc bis dimethyldithiocarbamate may form explosive dust-air mixtures.

Contact allergens
Ziram is a rubber vulcanization accelerator of the
dithiocarbamate group. Sensitization was reported in
several patients. Ziram is also used as a fungicide and
can cause contact dermatitis in agricultural workers.
Safety Profile
Poison by ingestion,intraperitoneal, and intravenous routes. Moderately toxicby inhalation. Questionable carcinogen with experimentalcarcinogenic and tumorigenic data. An experimentalteratogen. Other experimental reproductive effects.Human mutation d
Metabolic pathway
Ziram is one of the metal containing dithiocarbamates which generates
dimethyldithiocarbamic acid by being cleaved in acidic conditions and
in biological media. The resulting acid is conjugated with glucose and
alanine in plants and with glucuronic acid in mammals. Dimethyldithiocarbamic
acid is further degraded to dimethylamine and CS2. An extensive
review of the properties of dithiocarbamate pesticides was published
by the World Health Organisation (WHO, 1988) from which much of the
following information is taken.
Purification Methods
Crystallise this herbicide several times from hot toluene or from hot CHCl3 by addition of EtOH. [Beilstein 4 III 149, 4 IV 234.]
Degradation
Ziram is decomposed in acidic media and by UV irradiation (PM). Ziram
is stable in alkaline media but unstable in acidic conditions, decomposing
to dimethylamine and carbon disulfide.
Check Digit Verification of cas no
The CAS Registry Mumber 137-30-4 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 7 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 137-30:
(5*1)+(4*3)+(3*7)+(2*3)+(1*0)=44
44 % 10 = 4
So 137-30-4 is a valid CAS Registry Number.

Zinc(II) complexes with dithiocarbamato derivatives: Structural characterisation and biological assays on cancerous cell lines
Nagy, Eszter Márta,Sitran, Sergio,Montopoli, Monica,Favaro, Monica,Marchiò, Luciano,Caparrotta, Laura,Fregona, Dolores
, p. 131 - 139 (2012)
Zinc is one of the most important trace elements in the body and it is essential as a cofactor for the structure and function of a number of cellular molecules including enzymes, transcription factors, cellular signalling proteins and DNA repair enzymes. On the other hand, recent studies have shown that zinc could play a role both in the development of various cancers and in the induction of apoptosis in some cell types, however, no established common relationships of zinc with cancer development and progression have been identified. To date, in our research group different metal-dithiocarbamato complexes have been designed that were expected to resemble the main features of cisplatin together with higher activity, improved selectivity and bioavailability, and lower side-effects. On the basis of the obtained encouraging achievements with other metals (such as gold and copper) we have decided to enlarge the studies to the complexes of zinc(II) using the same ligands. Hereby, we report the results on the synthesis and characterisation of ZnL2 complexes with five different dithiocarbamato derivatives, such as dimethyl-(DMDT), pyrrolidine-(PyDT), methyl-(MSDT), ethyl-(ESDT) and tert-butyl-(TSDT) sarcosinedithiocarbamate. All the obtained compounds have fully been characterised by means of several spectroscopic techniques. In addition, the crystal structure of [Zn(MSDT)2]2 dinuclear complex is also reported. In order to evaluate the in vitro cytotoxic properties, some biological assays have been carried out on a panel of human tumour cell lines sensible and resistant to cisplatin. Some of the tested compounds show cytotoxicity levels comparable or even greater than the reference drug (cisplatin).
Gas-phase electron diffraction study of bis(dimethyldithiocarbamato)copper(II), [Cu(S2CNMe2)2], and bis(dimethyldithiocarbamato)zinc(II), [Zn(S2CNMe2)2]

The molecular structures of [Cu(S2CNMe2)2] and [Zn(S2CNMe2)2] have been studied by gas-phase electron diffraction. Both compounds are monomeric in the gas phase with the metal atoms being bound to two chelating [S2CNMe2] groups (rg(Cu-S) = 2.284 (9) ?; rg(Zn-S) = 2.348 (8) ?). The major difference between the two structures is in the geometry of the MS4 fragments, that of the copper compounds being pseudo square planar (D2h) while that of the zinc compound is pseudotetrahedral (D2d). The reason for the difference is attributed to the availability in the copper(II) compound of crystal field stabilization energy that is greater than the repulsive energy of the steric interactions imposed by the metal adopting a coordination sphere of D2h symmetry. Selected bond lengths and angles in the [S2CNMe2] groups are as follows (the data for the copper compound are quoted first with those for the zinc species being in brackets): rg(C-S) = 1.716 (10) ? [1.727 (10) ?]; rg(C=N) = 1.334 (18) ? [1.351 (17) ?]; rg(C-N) = 1.476 (18) ? [1.479 (17) ?]; ∠αS-M-S(chelate angle) = 78.78 (69)° [79.68 (59)°]; ∠αC=N-C = 124.9 (1.3)° [122.5 (1.2)°].
