Catalyst Titanium Tetraisopropanolate CAS 546-68-9 Chemical Auxiliary Agent Overview of Catalyst Titanium Tetraisopropanolate CAS 546-68-9 Chemical Auxiliary Agent Titanium isopropoxide has a complex structure. In the crystalline state, titanium isopropoxide is a tetramer. It does not polymerize in non-polar solvents and is a tetrahedral diamagnetic molecule. Titanium isopropylate, also known as titanium isopropoxide or titanium tetraisopropoxide, is the isopropoxide salt of

Plasticizers Trimellitic Anhydride CAS 552-30-7 Chemical Auxiliary Agent Overview of Plasticizers Trimellitic Anhydride CAS 552-30-7 Chemical Auxiliary Agent White powder or flakes. Melting point 168℃. Soluble in water and common organic solvents such as ethanol and aceton. It can be obtained by first obtaining benzenetricarboxylic acid from pseudocumene (mainly 1,2,4-trimethylbenzene) in the carbon nine fraction of aromatic hydrocarbons such as coal tar fraction, cracked

White Powder Sodium Triacetoxyborohydride CAS 56553-60-7 Catalyst Overview of White Powder Sodium Triacetoxyborohydride CAS 56553-60-7 Catalyst Sodium triacetoxyborohydride is easily soluble in benzene and tetrahydrofuran, soluble in acetonitrile and 1,2-dichloroethane and highly polar organic solvents. However, it has poor solubility in ethe solvents such as diethyl ethe, and the compound can react chemically with water. Product Parameters of White Powder Sodium Triacetoxybo

Colorless Liquid 2-Ethylhexyl Nitrate CAS 27247-96-7 Diesel Fuel Additive Overview of Colorless Liquid 2-Ethylhexyl Nitrate CAS 27247-96-7 Diesel Fuel Additive 2-Ethylhexyl nitrate is an important additive to improve the cetane number of diesel. Under low temperature conditions, isooctyl nitrate is decomposed by heat to produce active free radicals, which can trigger a series of oxidation chain reactions. Product Parameters of Colorless Liquid 2-Ethylhexyl Nitrate CAS 27247

Peptide synthesis protectant Chemical Auxiliary Agent Triisopropylsilane CAS 6485-79-6 Introduction: Colorless liquid, B.P.84-85℃(35mmHg), F.P.35℃,d 0.773.nD201.4340. This product is flammable and irritating Uses: Protecting agent for peptide synthesis. The bulky isopropyl group (compared to the ethyl group) enables more selective reduction reactions (e.g., β-selective reduction of anomeric C-phenyl ketals) without reducing their activity (e.g., trifluoromethanesulfonate

Crosslinking agent Chemical Auxiliary Agent Methyltrimethoxysilane CAS 1185-55-3 Silicone resin raw materials Introduction: Colorless liquid, methyltrimethoxysilane is a trifunctional organic silane coupling agent, because its three alkoxy groups can be hydrolyzed, and it contains a methyl group, which gives the product organic properties. Its function, like other silane coupling agents, relies on its own two reactive functional groups to combine two materials of different
