Description
Chlorophyll B is a phytochemical reference material supplied as ROTICHROM® CHR grade with a minimum purity of 90 % for chromatographic and analytical work. It has the empirical formula C₅₅H₇₀MgN₄O₆, a molar mass of 907,46 g/mol and CAS number 519-62-0, supporting identification and calibration tasks involving plant pigments. The product is offered as a powder in a 5 mg glass pack, suitable for standards preparation in chromatography and related phytochemical studies. Laboratories use chlorophyll B when building or verifying methods for natural-product analysis, pigment profiling and teaching or research applications that require a defined chlorophyll standard. This material from manufacturer Carl ROTH belongs to the ROTICHROM® CHR range for analytical chemicals and chromatography standards. Clear specification of purity, formula and pack format helps integrate the reagent into existing workflows for environmental, botanical and analytical laboratories handling chlorophyll-related measurements.
This article belongs on Chromatography standards (GC, HPLC, pesticides), in Analytical standards & reference materials.

Questions about Chlorophyll B, ROTICHROM® CHR, 5 mg, glass
What is this article?
Chlorophyll B, ROTICHROM® CHR, 5 mg, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Chromatography standards (GC, HPLC, pesticides), inside Analytical standards & reference materials, in Lab chemicals.
A chromatography standard is the substance, or the mix, injected so a peak can be named and quantified. Pesticide mixes, residual-solvent mixes and single-compound standards are different articles. The concentration and the solvent are the specification. The solvent has to be one the method may contain.
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.
