This organotungsten nitrosyl complex is a core homogeneous catalyst precursor and organometallic synthetic building block exclusively for fine chemical & academic R&D instead of pharmaceutical or food raw material. Dominantly applied in organometallic laboratory synthesis for constructing diverse tungsten-centered coordination complexes via nucleophilic substitution on labile chloride ligand; common substitutions include alkyl, aryl, alkoxide and amine groups to prepare functionalized CpW(NO)? derivatives. In catalytic chemistry research, it acts as precatalyst for alkene hydrofunctionalization, alkyne cyclization and carbonyl hydrogenation exploratory screening, widely adopted by university inorganic chemistry labs for catalytic mechanism study of transition metal nitrosyl species. High-purity certified grade serves as reference standard for NMR, IR and elemental analysis calibration during organometallic raw material QC inspection. Besides, it is used for precursor preparation of tungsten-based thin-film deposition precursors via ligand modification in material science labs researching metallic CVD coating materials.
Classified as GHS Warning hazard grade with H315 skin corrosion irritation, H319 severe eye damage, H335 harmful if inhaled fine crystal dust. All operators must equip butyl chemical resistant gloves, full-face protective goggles and dust-proof lab coat during weighing, sampling and solution preparation to avoid skin/mucosa direct contact and dust inhalation. Upon accidental skin or eye splash, continuously rinse contaminated area with abundant running clean water for minimum 15 min and consult medical treatment for persistent irritation symptoms. Accidental oral ingestion may trigger gastrointestinal ache, nausea and vomiting; immediate emergency hospital check is required for large-dose intake. All residual solid waste and organic waste liquid containing tungsten complex are categorized as heavy-metal hazardous waste, delivered to licensed professional hazardous waste treatment facility per local environmental regulation, forbidden to discharge into sewer or domestic trash. Keep separate storage from strong oxidants, concentrated acid and alkaline reagents to prevent exothermic decomposition and toxic nitrous oxide gas release under incompatible storage condition.
