Nitric acid, diluted, lead-free

Nitric acid, diluted, lead-free is a pharmacopoeia reagent prepared as Reag. Ph. Eur., Chapter 4.1.1, reference 1058406. It is nitric acid with empirical formula HNO₃, CAS number 7697-37-2 and EG nr. 231-714-2, and a molar mass of 63,01 g/mol. The lead-free, diluted grade is supplied in a 100 ml pack and is characterised by a density of 1,026 g/cm³ and a boiling point of 83 °C. These physical constants support identification and laboratory documentation of the reagent. The product belongs to the European Pharmacopoeia reagents of chapter 4.1.1, where diluted nitric acid free from lead is specified. A 100 ml unit suits controlled dispensing in analytical workflows that follow Ph. Eur. methods. The acid is available from manufacturer Carl ROTH with UN number 2031. Formula HNO₃ and molar mass 63,01 g/mol confirm the chemical identity of the nitric acid component, while the diluted, lead-free specification defines the intended pharmacopoeial use. Density 1,026 g/cm³ and boiling point 83 °C complete the physicochemical profile given for this listing.
