Photoinitiator 183 (1-Hydroxycyclohexyl phenyl ketone) is a white crystalline powder used in photopolymerization. It absorbs UV light and converts it into chemical energy, initiating polymerization by creating free radicals. Here's a more detailed breakdown:Chemical Properties:

• Chemical Formula: C13H16O2
• CAS Number: 947-19-3
• Molecular Weight: 204.26
• Melting Point: 47-50 °C
• Boiling Point: 175 °C/15 mmHg
• Flash Point: > 150 °C
• Density: 1.17 g/cm3
• Solubility: Slightly soluble in water, but soluble in acetone, butyl acetate, methanol, and toluene 

Function:Photoinitiators, like 183, are essential components in photopolymerization processes. They are activated by UV light, generating free radicals that then initiate the polymerization of monomers, forming a cross-linked polymer. This process is used in various applications, including photoimaging, UV curing of coatings and inks, and 3D printing

Benzophenone hydrazone is used as an intermediate in synthesizing pharmaceuticals, dyes, and pigments. It is also used as an analytical reagent, a photoinitiator in UV-curing applications like inks and coatings, and as a starting material for other chemical compounds like indole and diphenyldiazomethane. Additionally, it can function as a light stabilizer, metal chelator, and a component in optoelectronic materials. 

Industrial and laboratory uses

• UV-curing: It acts as a photoinitiator in UV-curable inks, adhesives, and coatings.
• Light stabilizers: Its UV-absorbing properties allow it to be used in plastics to protect them from UV degradation.
• Analytical chemistry: It serves as a reagent for separating and detecting metal ions due to its ability to form stable complexes with metals like copper, iron, and cobalt.
• Optoelectronics: Its photoluminescent properties make it a candidate for use in developing materials for organic light-emitting diodes (OLEDs) and solar cells.
• Catalysis: Complexes formed with metal ions can be used to improve the efficiency of certain organic reactions.
