Description
Lasiocarpine is a defined reference compound offered as ROTICHROM® HPLC material for chromatographic and analytical laboratory use. It carries CAS number 303-34-4 and the empirical formula C₂₁H₃₃NO₇, with a molar mass of 441,49 g/mol. The substance is supplied in a 10 mg glass pack, appropriate for method development, calibration support, and comparative HPLC work where only small quantities are required. UN number 2811 applies to transport classification as indicated by the manufacturer data. This lasiocarpine grade from manufacturer Carl ROTH is positioned within the ROTICHROM® HPLC line for laboratories that need a clearly specified pyrrolizidine alkaloid standard rather than bulk synthesis feedstock. Physical handling should follow the associated safety documentation and institutional protocols for potent organic solids. The compact glass presentation helps protect the contents during storage and dispensing on the analytical bench. Use is typical in natural-product analysis, toxicology-related chromatography, and quality-control settings that specify lasiocarpine under CAS 303-34-4 with the stated molecular parameters.
This article is part of HPLC & LC-MS grade solvents, in Solvents. See also Analytical grade solvents (p.a.).

Questions about Lasiocarpine, ROTICHROM® HPLC, 10 mg, glass
What is this article?
Lasiocarpine, ROTICHROM® HPLC, 10 mg, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in HPLC & LC-MS grade solvents, inside Solvents, in Lab chemicals.
HPLC grade limits the absorbance and the residue that would appear as peaks or baseline drift. LC-MS grade goes further on metal ions and on particles that would suppress a mass spectrum. A solvent that is only analytical grade is a false economy on an LC-MS system.
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.
Which category should I open next?
The category is Solvents. The sub-category is HPLC & LC-MS grade solvents. The catalogue is Lab chemicals.
