Beschrijving

Crystal violet (C.I. 42555) is een indicatorkleurstof van p.a.-kwaliteit met CAS-nummer 548-62-9 en empirische formule C₂₅H₃₀ClN₃. De molaire massa bedraagt 407.99 g/mol, de dichtheid 1.19 g/cm³, het vlampunt 405.1 °C en het kookpunt 631.9 °C, wat een duidelijk fysisch-chemisch profiel voor de methodeopzet geeft. De Colour Index-verwijzing C.I. 42555 ondersteunt een consistente specificatie in protocollen en registraties. Crystal violet van fabrikant Carl ROTH wordt geleverd in p.a.-kwaliteit voor gecontroleerd laboratoriumgebruik. EG-nummer 208-953-6 en UN-nummer 3077 ondersteunen de regelgevende en logistieke afhandeling. De glazen eenheid is praktisch voor het afwegen en het bereiden van oplossingen bij titratie- en indicatortoepassingen. Deze kleurstof is bedoeld voor analytische laboratoria die een goed gekarakteriseerd crystal violet-reagens nodig hebben voor pH-gerelateerde en verwante indicatorprocedures.

Dit artikel maakt deel uit van Oplosmiddelen van analytische kwaliteit (p.a.), in Oplosmiddelen.

Questions about Crystal violet (C.I. 42555), p.a., 25 g, glas

What is this article?

Crystal violet (C.I. 42555), p.a., 25 g, glas is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Oplosmiddelen van analytische kwaliteit (p.a.), inside Oplosmiddelen, in Chemicaliën.

An analytical-grade solvent, often marked p.a., has impurity limits tight enough for classical analysis and for preparing reagents. It is not automatically low enough in UV absorbance for HPLC, and it is not dry enough for a water-sensitive reaction. The grade is the purchase.

A solvent dissolves. The grade says which impurities are low enough for the method. Analytical grade is the ordinary pure solvent. HPLC and LC-MS grades limit the absorbance and the ions that would become peaks or background. A dry solvent has had water removed. A deuterated solvent is for NMR, where the hydrogen signal would otherwise drown the sample. Technical grade is for cleaning and for synthesis that does not need a chromatogram. Identity is on PubChem. Names follow IUPAC. Hazards follow ECHA, the CLP Regulation and REACH.
