Description
Methyl red solution is a pharmacopoeia-quality chemical specified as Reag. Ph. Eur., Chapter 4.1.1, 1055102, supplied in a 100 ml plastic pack. It is used as the corresponding reagent in European Pharmacopoeia work that cites Chapter 4.1.1. Density is approximately 0,79 g/cm³, the flash point is 26 °C and the boiling point is 78 °C; the UN number is 1993. Laboratories obtain this methyl red solution from manufacturer Carl ROTH when they need the Ph. Eur. reagent of this name for analytical and quality-control procedures. The 100 ml plastic unit quantity is practical for documented pharmacopoeial methods that consume a moderate volume of reagent. The reported density of approximately 0,79 g/cm³ supports conversion between dispensed volume and mass in the analytical laboratory. Flash-point and boiling-point values of 26 °C and 78 °C support risk assessment and transport planning together with UN 1993. The article belongs to chemicals in pharmacopoeia quality, covering reagents and volumetric standard solutions (Ph. Eur.), Reagents 4.1.1. Reference 1055102 should be retained on orders and in method records to identify the correct Chapter 4.1.1 reagent.

Questions about Methyl red solution, Reag. Ph. Eur., Chapter 4.1.1, 100 ml, plastic
What is this article?
Methyl red solution, Reag. Ph. Eur., Chapter 4.1.1, 100 ml, 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.
