Description
Guaiacol is an extra pure aromatic compound supplied at min. 98 % purity for analytical and phytochemical laboratory work. Identified by CAS number 90-05-1 and EG nr. 201-964-7, it has the empirical formula C₇H₈O₂ and a molar mass of 124,14 g/mol. Physical data include a density of 1,13 g/cm³, a flash point of 90 °C and a boiling point of 205 °C, supporting controlled handling in synthesis, chromatography standards and natural-product studies. This grade is offered in a 100 ml glass pack, suited to routine preparation of reference solutions and method development. Guaiacol from manufacturer Carl ROTH fits workflows that require a clearly specified phenolic ether with documented composition. Categories such as analytical chemicals, chromatography standards and phytochemicals benefit from its defined purity and reproducible physicochemical profile. The material supports qualitative and quantitative applications where a reliable guaiacol source is needed without further purity claims beyond the stated minimum.
This article belongs on Reference substances & reagents (other), in Analytical standards & reference materials.

Questions about Guaiacol, min. 98 %, extra pure, 100 ml, glass
What is this article?
Guaiacol, min. 98 %, extra pure, 100 ml, 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.
