Description

Dioctyl phthalate purified is a high-purity grade of the plasticizer dioctyl phthalate (DOP), also known as bis(2-ethylhexyl) phthalate. It is typically supplied as a clear, colorless or slightly yellowish oily liquid with assay ≥99.5% and very low impurity/moisture content.​ Chemical properties Chemical name: Dioctyl phthalate Synonyms: Bis(2-ethylhexyl) phthalate, DEHP, DOP.​ CAS number: 117-81-7 (also 117-84-0 for di-n-octyl phthalate).​ Molecular formula: C₂₄H₃₈O₄.​ Molecular weight: ~390.54 g/mol.​ Appearance: Clear, colorless to light yellow oily liquid.​ Density: 0.985–0.988 g/mL at 20–25 °C.​ Boiling point: 384 °C.​ Melting point: −50 °C.​ Refractive index: 1.483–1.488 at 20–27 °C.​ Acid value: ≤0.01% as phthalic acid.​ Moisture content: ≤0.1%.​ Applications Used as a primary plasticizer in the manufacture of flexible PVC products, resins, elastomers, and rubber.​ Often selected for high-purity/plasticizer-sensitive applications including laboratory, medical device, and analytical reagent use where low UV absorbance and minimal impurities are necessary.​ Purification notes Highly purified DOP may be further processed to reduce levels of phthalide and UV-absorbing impurities, meeting ISO standards for medical applications.​ Typical methods involve filtration or adsorption (activated carbon, silica gel, diatomaceous earth) to remove color bodies and phthalide by-products, resulting in DOP with UV absorbance <0.1 at 230 nm.​ Safety and handling Store in tightly closed containers at room temperature, away from heat and strong oxidizers.​ Handle with appropriate PPE due to potential health and environmental risks; not for food, drug or cosmetic use.​

Ferrous Ammonium Sulphate Extra Pure (also known as Ammonium Iron(II) Sulfate Hexahydrate or Mohr's Salt) is a pale green to blue-green crystalline solid with the chemical formula FeSO4(NH4)2SO4·6H2O. It is supplied in extra pure grade with high chemical purity, typically 98.5% and above, suitable for analytical and research applications requiring precise and reliable chemical reagents.​ Description for Website Ferrous Ammonium Sulphate Extra Pure is a high-purity crystalline compound of ammonium, iron(II), and sulfate ions, stabilized as a hexahydrate. It is widely used as a primary standard in analytical chemistry for redox titrations due to its stability against oxidation compared to regular iron(II) salts. Its light blue-green crystals are odorless and dissolve readily in water. This reagent is also utilized in dosimetry for measuring gamma radiation exposure, nanomaterials synthesis, and medical applications for iron deficiency treatment.​ Key Features Chemical formula: FeSO4(NH4)2SO4·6H2O Appearance: Pale green to blue-green crystalline powder or crystals Purity: Extra pure grade (typically ≥98.5%) Solubility: Highly soluble in water; stable in air due to ammonium sulfate stabilization Applications: Analytical reagent for redox titrations, primary standard, dosimetry, nanomaterial synthesis, and medical use as an iron supplement Handling: Store in a cool, dry place protected from light; sensitive to air oxidation but more stable than simple ferrous sulfate​ Safety and Stability Extra pure ferrous ammonium sulfate is stable under recommended storage conditions but is sensitive to light and air over long periods. Proper storage and handling practices are recommended to maintain reagent quality.​ This description provides a professional summary suitable for product listings, catalogs, or websites targeting laboratory and industrial customers who require high-purity ferrous ammonium sulfate for precise chemical applications.​
