Description
Hydroquinone solution is a pharmacopoeia-quality reagent specified as Reag. Ph. Eur., Chapter 4.1.1, 1044101, with CAS number 123-31-9 and the empirical formula C₆H₆O₂. The hydroquinone constituent is further identified by EG number 204-617-8 and a molar mass of 110,11 g/mol; density is approximately 1 g/cm³ and the boiling point is 100 °C. A 100 ml plastic bottle provides a practical pack for laboratories that prepare or apply European Pharmacopoeia reagents from Chapter 4.1.1. This solution from manufacturer Carl ROTH is intended for pharmacopoeial reagent use rather than as an unspecified bulk chemical, supporting analytical work that cites the Ph. Eur. hydroquinone solution 1044101. Presentation in plastic supports routine dispensing at the bench, while the stated physical data assist inventory, SOP writing and method documentation. Molar mass, density and boiling point are recorded so users can cross-check handling conditions against their own procedures. The CAS number 123-31-9 and formula C₆H₆O₂ remain the chemical identity anchors for the hydroquinone component throughout purchasing and laboratory records.

Questions about Hydroquinone solution, Reag. Ph. Eur., Chapter 4.1.1, 100 ml
What is this article?
Hydroquinone solution, Reag. Ph. Eur., Chapter 4.1.1, 100 ml is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Reagents for analysis (Ph. Eur., ASTM, DIN), inside Analytical standards & reference materials, in Lab chemicals.
A reagent for analysis is a chemical whose impurities are limited so they do not become a signal in a titration, a digestion or a photometric method. Pharmacopoeia, ASTM and DIN names point at different limit lists. The grade, not only the identity, is the purchase.
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.
