LS-PTCR Bis(triphenylsilyl)chromate
CAS NO.: 1624-02-8

Name: LS-PTCR Bis(triphenylsilyl)chromate
Brand: Nanjing Silfluo New Material Co., Ltd.
Availability: InStock

Silfluo LS-PTCR is Bis(triphenylsilyl)chromate, an organochromium(VI) coordination complex.

The molecule contains a hexavalent chromium center covalently bonded to two triphenylsilyloxy groups via Cr–O–Si linkages.

The triphenylsilyl ligands provide steric bulk and thermal stability; the Cr(VI) center is the catalytically and chemically active site.

Used as catalyst precursor in supported chromium catalyst systems for ethylene polymerization (Phillips / Union Carbide type), and as selective oxidizing reagent in pharmaceutical and fine chemical synthesis.
