Description
Sodium hydroxide solution is an aqueous laboratory reagent of Reag. Ph. Eur. quality (Chapter 4.1.1, 1081407) with CAS number 1310-73-2, empirical formula NaOH and molar mass 40,01 g/mol. The product is packed as 1 l in plastic and is characterised by a density of 1,17 g/cm³ and a boiling point above 100 °C. It is used in pharmacopoeial and related analytical work that specifies sodium hydroxide solution as a Chapter 4.1.1 reagent, for example in alkaline reaction media, titrimetry and sample preparation. Data from manufacturer Carl ROTH also list EG number 215-185-5 and UN number 1824, which help laboratories document chemical identity in their quality records. The 1 litre plastic pack supports convenient dispensing for routine bench applications. Density and molar mass enable calculation of transferred amounts when the solution is measured by volume or mass. This reagent is intended for controlled laboratory and pharmacopoeial testing in line with the stated Ph. Eur. chapter, providing a clearly identified sodium hydroxide solution for methods that require this grade.

Questions about Sodium hydroxide solution, Reag. Ph. Eur., 1 l, plastic
What is this article?
Sodium hydroxide solution, Reag. Ph. Eur., 1 l, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Reference substances & reagents (other), inside Analytical standards & reference materials, in Lab chemicals.
A reference substance has a stated identity and a stated content, used to check a method or to standardise a titration. It is a more tightly specified article than a reagent grade bottle of the same name. The lot's certificate is part of the product.
A reference material is the article against which another result is compared. Its value is stated, and the uncertainty of that value is part of the product. An ICP or ion standard is a solution of known concentration. A volumetric standard is for titration. A chromatography standard is the peak you match. The grade names, including pharmacopoeia and ASTM, say which impurities were limited. Identity is checked on PubChem. Names follow IUPAC. Medicinal grades follow the European Pharmacopoeia and USP.
Which category should I open next?
The category is Analytical standards & reference materials. The sub-category is Reference substances & reagents (other). The catalogue is Lab chemicals.
Shelves beside this one are ICP, AAS & ion standards, Chromatography standards (GC, HPLC, pesticides), Volumetric standard solutions (titration), Reagents for analysis (Ph. Eur., ASTM, DIN), Spectroscopy & physical property standards and Indicators & indicator solutions.
What should I check before I order?
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.
