Basic Info
Benzophenone Products is a typical aromatic ketone compound with a chemical formula of C₁₃H₁₀O. The molecular structure is composed of two phenyl groups connected by a carbonyl group (C=O), and it belongs to the diaryl ketone class of substances. It usually appears as a white crystalline powder or flaky crystal with a special aromatic smell. Its melting point is about 48.5℃ and its boiling point is 297℃. It is easily soluble in organic solvents such as ethanol, ether, and chloroform, but difficult to dissolve in water. Due to the presence of conjugated phenyl and carbonyl systems in the molecule, it has a certain absorption capacity for ultraviolet light.
The carbonyl group in benzophenone products exhibits typical electrophilic properties. It can undergo nucleophilic reactions, such as addition reactions with Grignard reagents or alcohols. The benzene ring in the molecule can undergo aromatic ring substitution reactions, such as halogenation. Due to these characteristics, it is an important organic intermediate. Benzophenone products can undergo photochemical reactions under light, and the carbonyl groups excited by these reactions can be used to initiate polymerization or photooxidation reactions. This characteristic is closely related to its application in ultraviolet light absorption.

Photoinitiator Field
Benzophenone Products is a commonly used photoinitiator in ultraviolet (UV) curing systems. Its molecules are excited to the triplet state under ultraviolet light, and the polymerization of monomers is initiated by hydrogen abstraction or direct initiation. For example, in the UV curing process of coatings, inks and adhesives, benzophenone absorbs 250-360nm ultraviolet light and synergizes with amine co-initiators to produce active free radicals, which promote the rapid cross-linking of acrylate monomers to form films. It can be used for rapid drying of wood paint and printed circuit board inks to improve production efficiency.
Ultraviolet Absorber Field
As ultraviolet absorbers, Benzophenone Products and its derivatives (such as 2-hydroxybenzophenone) can effectively absorb ultraviolet rays with a wavelength of 280-400nm and are commonly used in plastics, rubber, coatings and cosmetics. For example, adding Benzophenone Products compounds to polymer materials such as polyethylene and polypropylene can inhibit the degradation of polymer chains caused by ultraviolet rays and extend the weather resistance of the products; in sunscreen, its derivatives absorb UVB band ultraviolet rays through a conjugated system, reduce the damage of ultraviolet rays to the skin, and have good photostability and safety.
Organic Synthesis and Pharmaceutical Intermediates
The carbonyl and aromatic ring structures of Benzophenone Products make it an important intermediate in organic synthesis. In drug synthesis, it can be used to prepare antihistamines, antidepressants, etc. through Grignard reaction, reductive amination and other reactions; for example, benzophenone hydrazone compounds synthesized from benzophenone as raw materials can be used as intermediates for antibacterial drugs. In addition, its derivatives can be used to construct biologically active molecular skeletons, such as the synthesis of antitumor drugs or enzyme inhibitors, by introducing groups such as hydroxyl groups and halogen groups.
Flavors and Fragrances
Benzophenone Products has a sweet and mellow floral and fruity aroma, and is often used as a synthetic fragrance in the formulation of daily chemical fragrances. Its aroma is similar to almonds and cherries. It can be paired with vanillin, phenylethanol, etc., and used in cosmetics (such as creams, perfumes) and edible flavors (such as candies, baked goods) to give the products a warm sweet base tone. In addition, its derivatives such as methyl benzophenone can enhance the persistence and diffusion of the aroma, and are often used to formulate floral or oriental flavors.
Field of Fine Chemicals and Analytical Reagents
In fine chemicals, Benzophenone Products can be used as a photosensitizer for photochemical reactions, such as photocatalytic synthesis or preparation of photochromic materials; it can also be used as a solvent for organometallic reactions (such as synthesis involving lithium reagents). In analytical chemistry, it is used as a standard substance for quantitative analysis of high-performance liquid chromatography (HPLC) or ultraviolet spectroscopy (UV-Vis), and can also be used to detect the photochemical behavior of certain compounds, such as as a model substrate for photooxidation reactions to study the mechanism of free radical reactions.
