Description
Phthalic anhydride is an organic reagent offered at minimum 98 % purity for synthesis, identified by CAS number 85-44-9 and the empirical formula C₈H₄O₃. With a molar mass of 148,12 g/mol and a density of 1,53 g/cm³, it presents a well-defined solid profile for stoichiometric work. The flash point is 152 °C and the boiling point is 284,5 °C, supporting predictable thermal handling in controlled laboratory settings. This variant is Physical and identity data from manufacturer Carl ROTH align with standard documentation needs for process development and quality records. Typical laboratory use includes routes toward plasticizers, resins, dyes and related carbonyl-containing building blocks where a high-assay anhydride is required. The substance is further referenced by EG number 201-607-5 and UN number 2214. Clear molar mass, density and boiling-point values help chemists plan reaction conditions, solvent choice and work-up steps with consistency across batches.

Questions about Phthalic anhydride, min. 98 %, for synthesis, 250 g, plastic
What is this article?
Phthalic anhydride, min. 98 %, for synthesis, 250 g, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Inorganic salts, inside Inorganic chemicals, in Lab chemicals.
An inorganic salt is an ionic solid, a chloride, a sulfate, a nitrate, a phosphate. The degree of hydration changes the mass that contains one mole of the ion. Analytical grade limits the foreign ions. A hydrate and the anhydrous salt are not interchangeable by weight.
An inorganic chemical is a salt, an acid or base in solid form, a metal, an oxide, or an element. The waters of hydration are part of the formula: a hydrate and an anhydrous salt are different masses for the same ion. Trace metals matter when the salt will be used in analysis. Nanomaterials add particle size to the specification. Look the substance up on PubChem. Hazard classes are on ECHA, under the CLP Regulation and REACH. Transport of the dangerous ones is explained by the UNECE.
