Description
Chlorophyll A is a powdered phytochemical reference material with CAS number 479-61-8 and empirical formula C₅₅H₇₂MgN₄O₅. Its molar mass of 893,48 g/mol makes it a well-defined standard for analytical work on plant pigments and related natural products. Laboratories use it in method development, calibration, and qualitative or quantitative studies of photosynthetic pigments within analytical chemistry workflows. The material is supplied by manufacturer Carl ROTH and fits catalogues covering analytical chemicals and standards for chromatography. Clear CAS and EG identification (EG nr. 207-536-6) support traceable documentation in regulated and research environments. The compact glass pack size is practical for reference stock and low-consumption assays, helping laboratories maintain consistent pigment standards without excess inventory.
This article is part of Reference substances & reagents (other), in Analytical standards & reference materials.

Questions about Chlorophyll A, powder, 1 mg, glass
What is this article?
Chlorophyll A, powder, 1 mg, 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.
