Description
Herniarin is a phytochemical reference substance offered as ROTICHROM® CHR with a minimum assay of 98 %, CAS number 531-59-9, EG number 208-513-3 and empirical formula C₁₀H₈O₃. Its molar mass is 176,17 g/mol, supporting accurate preparation of calibration solutions and chromatographic standards. Packed as 1 g in glass, the material is intended for analytical chemistry workflows that require a defined coumarin-type marker, including standards for chromatography and phytochemical profiling. Herniarin is widely recognised as 7-methoxycoumarin and is used where identity confirmation, peak assignment or quantitative comparison against a high-purity solid is needed. This ROTICHROM® CHR grade from manufacturer Carl ROTH fits laboratories working on plant extracts, natural-product analysis and method validation that depend on documented purity and molecular formula. The compact glass unit facilitates precise weighing for stock standards while limiting unnecessary bulk in analytical inventories. Clear CAS, EG and molar-mass data streamline registration in LIMS and reagent databases for chromatography and related separation techniques without extending beyond the stated analytical specification.
This article is part of Reference substances & reagents (other), in Analytical standards & reference materials.

Questions about Herniarin, ROTICHROM® CHR, 1 g, glass
What is this article?
Herniarin, ROTICHROM® CHR, 1 g, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Reference substances & reagents (other), inside Analytical standards & reference materials, in Lab chemicals.
A reference substance has a stated identity and a stated content, used to check a method or to standardise a titration. It is a more tightly specified article than a reagent grade bottle of the same name. The lot's certificate is part of the product.
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.
Which category should I open next?
The category is Analytical standards & reference materials. The sub-category is Reference substances & reagents (other). The catalogue is Lab chemicals.
Shelves beside this one are ICP, AAS & ion standards, Chromatography standards (GC, HPLC, pesticides), Volumetric standard solutions (titration), Reagents for analysis (Ph. Eur., ASTM, DIN), Spectroscopy & physical property standards and Indicators & indicator solutions.
What should I check before I order?
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
