Xylene special (mixture of isomers) AR 2.5 L

Xylene special (mixture of isomers) AR 2.5 L

SKU : B-3108.2500

CAS : 1330-20-7

Formula : C8H10

Grade : Analytical Reagent

Primary Uses :

Histology & Cytology: The “Special” grade is the gold standard for tissue processing and staining. It acts as a superior “clearing agent” to remove alcohol from tissue samples before they are embedded in paraffin wax.
Analytical Chemistry: Used as a solvent in Gas Chromatography (GC) and spectrophotometry where the absence of high ethylbenzene levels ensures cleaner baselines and more precise peaks.
Microscopy: Used to clean microscope objectives and as a solvent for mounting media when preparing permanent slides.
Specialized Synthesis: Acts as a reaction medium for organic chemistry where the presence of ethylbenzene might cause unwanted side reactions or affect the solubility of the final product.

Why “Low Ethylbenzene” Matters :

Ethylbenzene has a slightly different reactivity and boiling point than the xylene isomers. In delicate histological staining (like H&E staining), high ethylbenzene can cause tissue shrinkage or inconsistent “clearing,” leading to poor diagnostic quality under the microscope.

Xylene or Xylol (IUPAC name: dimethylbenzene) are any of three organic compounds with the formula (CH₃)₂C₆H₄. They are derived from the substitution of two hydrogen atoms with methyl groups in a benzene ring ; which hydrogens are substituted determines which of three structural isomers results. It is a colorless, flammable, slightly greasy liquid of great industrial value.

The mixture is referred to as both xylene and, more precisely, xylenes. Mixed xylenes refers to a mixture of the xylenes plus ethylbenzene. The four compounds have identical molecular formulas C₈H₁₀. Typically the four compounds are produced together by various catalytic reforming and pyrolysis methods.

Xylene Special AR (Mixture of Isomers) is a high-purity laboratory reagent consisting of the three xylene isomers (ortho-, meta-, and para-) with a strictly controlled low level of ethylbenzene (typically < 3%).

Standard “Laboratory Reagent” (LR) xylene often contains up to 20-25% ethylbenzene, but the AR (Analytical Reagent) “Special” grade is refined to minimize this impurity for more accurate chemical analysis and sensitive applications.
