As an organosilicon compound with high refractive index properties, IOTA 259A has continuously gained applications in subdivided fields such as optical materials, pharmaceutical intermediates and fine chemical synthesis in recent years, relying on its stable physical and chemical properties.
The typical physical and chemical parameters of IOTA 259A are as follows:
-
Refractive index (25℃): 1.598
-
Melting point: 46–49 °C
-
Boiling point: 215 °C
-
Density: 1.076 g/cm³
-
Flash point: 193 °C (closed cup)
-

This product does not belong to traditional silicone oil-based lubricating or damping media, but is more often used as a functional intermediate or high refractive index additive. Its high refractive index is close to that of some optical resins and glass materials, and it has certain value in experiments and production that require light path adjustment, light transmittance matching improvement or high refractive coating preparation.
Currently, IOTA 259A is mainly used in the following directions:
-
Formulation component of optical adhesives and packaging materials
-
Synthetic precursor of high refractive index organosilicon monomers
-
Structural intermediate in pharmaceutical and agricultural chemicals
-
R&D and small-batch preparation of special fine chemicals
According to feedback from some scientific research institutions and fine chemical enterprises, IOTA 259A has shown good batch consistency and reaction controllability in laboratory synthesis and pilot-scale amplification processes, with low impurity content, which is convenient for subsequent purification treatment.
The manufacturer stated that the product has achieved standardized production, supports gram-level to kilogram-level supply, and provides Certificate of Analysis (CoA) and Safety Data Sheet (SDS). The product complies with conventional chemical management standards and is suitable for R&D, small-batch customization and compliant industrial applications.
With the growing demand for high-purity and high-functional intermediates in fields such as optoelectronics and biomedicine, special silicon-based compounds with clear physical property indicators such as IOTA 259A are gradually becoming one of the reliable options in the material innovation chain.
Note: IOTA 259A is a product that has been commercialized for many years, mainly positioned as a chemical reagent and intermediate, not for lubrication or engineering fluid purposes. It is suitable for R&D and production scenarios requiring high refractive index or specific molecular structure.
