Hydroquinone solution, Reag. Ph. Eur., Chapter 4.1.1, 100 ml

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.
