Description
Boric acid is a high-purity inorganic acid meeting min. 99,5 % content and Ph.Eur., USP and BP pharmacopoeia requirements. Its empirical formula is H₃BO₃, with CAS number 10043-35-3, EG nr. 233-139-2, a molar mass of 61,83 g/mol and a density of 1,489 g/cm³. The reagent is valued in pharmaceutical formulation support, buffer preparation, analytical chemistry and laboratory applications that call for pharmacopoeia-grade boric acid. This quality grade from manufacturer Carl ROTH aligns with monographs used in European and US pharmacopoeial practice, helping laboratories maintain traceable acid and base stocks. Typical uses include pH adjustment systems, complexation chemistry and reference preparations where defined purity and identity are essential. The crystalline solid integrates readily into standard wet-lab workflows for research, QC and teaching environments.
This article is part of Acids, in Acids & bases.

Questions about Boric acid, min. 99,5 %, Ph.Eur., USP, BP, 500 g, plastic
What is this article?
Boric acid, min. 99,5 %, Ph.Eur., USP, BP, 500 g, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Acids, inside Acids & bases, in Produits chimiques.
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.
Which category should I open next?
The category is Acids & bases. The sub-category is Acids. The catalogue is Produits chimiques.
Shelves beside this one are Bases & alkalis.
What should I check before I order?
The technical information on this page is the manufacturer's sheet. Read that, not a rewritten specification.
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
