Description
DL-alpha-Tocopherol is an oily vitamin E compound supplied at a minimum purity of 96 % in Ph.Eur. quality for pharmaceutical and biochemical laboratory use. The substance carries CAS number 10191-41-0 and EG nr. 233-466-0, with the empirical formula C₂₉H₅₀O₂ and a molar mass of 430,72 g/mol. Reported physical properties include a density of 0,95 g/cm³, a flash point above 113 °C and a boiling range of 200 to 220 °C, supporting clear documentation in safety and process files. DL-α-tocopherol is frequently applied in antioxidant and vitamin research, stability assessments and quality-control protocols that call for Ph.Eur. grade material. The product is available from manufacturer Carl ROTH within the vitamins range for chemicals in pharmacopoeia quality. Defined purity, oily form and full chemical identity data enable laboratories to specify the reagent consistently across methods and records.

Questions about DL-alpha-Tocopherol, min. 96 %, Ph.Eur., oily, 25 g, glass
What is this article?
DL-alpha-Tocopherol, min. 96 %, Ph.Eur., oily, 25 g, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Coenzymes, nucleotides & vitamins, inside Biochemicals & reagents, in Life Science & Microbiology.
Coenzymes, nucleotides and vitamins are the small molecules enzymes and cells consume: NAD, ATP, a vitamin cofactor. Purity, salt form and hydration are the specification, and many are unstable in solution or in the light. The lot is stored as the label says, often cold.
A biochemical is a molecule of life, sold as a reagent: an amino acid, a sugar, a nucleotide, a lipid, an enzyme, an antibiotic. The difference from a bulk chemical is that the use is a biological one, and the impurities that matter are the ones that change that use. An enzyme is specified by activity, not only by mass. An antibiotic is specified by potency. Papers are on PubMed. Structures are on PubChem. Strains and lines that consume these reagents are at ATCC.
