94442-22-5 Usage
Uses
Different sources of media describe the Uses of 94442-22-5 differently. You can refer to the following data:
1. Platinum complex widely used in CVD and ALD applications due, in part, to its simplicity (only C,H and Pt), volatility and moderate decomposition temperatures.
2. (Trimethyl)methylcyclopentadienylplatinum(IV) was used for the deposition of ultrathin metallic layers of platinum by electron beam induced deposition, atomic sputtering.These deposits find application in microelectronics, catalysis, photonics and chemical sensing.
3. Trimethyl(methylcyclopentadienyl)platinum(IV) is used as an organometallic precursor for platinum. It is used in the microelectronics, catalysis, photonics and chemical sensing processes. It is used for the deposition of ultrathin metallic layers of platinum by the electron beam induced deposition process.
General Description
Trimethyl(methyl cyclopentadienyl)platinum(IV) ( MeCpPtMe3) is a commonly used organometallic precursor for platinum.
Check Digit Verification of cas no
The CAS Registry Mumber 94442-22-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,4,4 and 2 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 94442-22:
(7*9)+(6*4)+(5*4)+(4*4)+(3*2)+(2*2)+(1*2)=135
135 % 10 = 5
So 94442-22-5 is a valid CAS Registry Number.

Weakly-coordinated stable platinum nanocrystals
Marquardt, Dorothea,Barthel, Juri,Braun, Markus,Ganter, Christian,Janiak, Christoph
, p. 7607 - 7615 (2013/01/15)
Stable platinum nanocrystals with small diameters (1.0-2.3 nm), that are stable for a long time, with narrow size distributions were easily and reproducibly prepared without any additional stabilizers in glycol, glycerol, the ionic liquids (ILs) 1-n-butyl-3-methyl-imidazolium tetrafluoroborate [BMIm][BF4] and N-butyl-N-trimethyl-ammonium bis(trifluoromethylsulfonyl)imide [N4111][NTf2] or diphenylmethane (CH2Ph2) by thermal, photolytic or microwave assisted decomposition of the organometallic precursor methylcyclopentadienyl-trimethylplatinum(iv), (MeCp)PtMe3. Decomposition of the easily dispensible, air and moisture stable organometallic Pt(iv) precursor (MeCp)PtMe3 leads to well defined, small, crystalline and longterm stable Pt-nanoparticle (Pt-NP) dispersions without any additional surface-capping ligands. The Pt-NP/IL dispersion was shown to be a highly active catalyst (TOF 96000 h-1 at 0.0125 mol% Pt and quantitative conversion) for the biphasic hydrosilylation of phenylacetylene with triethylsilane, to the distal and proximal products triethyl(2- and1-phenylvinyl)silane.
