Description
Phthalic acid is an aromatic dicarboxylic acid offered at min. 99 % purity in p.a. quality for analytical and general laboratory chemistry. It is identified by CAS number 88-99-3, EG number 201-873-2 and the empirical formula C₈H₄O₄, with a molar mass of 166,13 g/mol. Physical data include a density of 1,59 g/cm³, a flash point of 168 °C and a boiling point of 289 °C, supporting safe handling assessments in controlled lab environments. This grade is Phthalic acid from manufacturer Carl ROTH is a practical choice for chemical inventories covering A-to-Z laboratory reagents. The solid is intended for trained users who need a consistent p.a. material for routine experimental protocols, calibration-related preparations and broader organic chemistry applications without extending beyond the stated analytical specification.

Questions about Phthalic acid, min. 99 %, p.a, 100 g, plastic
What is this article?
Phthalic acid, min. 99 %, p.a, 100 g, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Acids, inside Acids & bases, in Lab chemicals.
An acid on this shelf is the substance itself, concentrated or as a stated solution: hydrochloric, sulfuric, nitric, acetic and the rest. Concentration, purity and the trace metals decide the use. A concentrated acid and a volumetric solution of the same name are different products, and both burn.
An acid donates a proton. A base accepts one. In the bottle, the practical differences are the concentration, the purity and the anion or cation that comes along. Concentrated mineral acids are a different article from a dilute volumetric solution. The water in the acid, and the trace metals, decide whether it can be used for analysis. Check the substance on PubChem and the classification on ECHA CLP. Transport is the UNECE dangerous-goods framework. The legal texts are the CLP Regulation and REACH.
