Description
Silyl-991 is a silylating agent presented in a multi-vial pack for chromatography sample preparation. With CAS numbers 25561-30-2 and 75-77-4, the reagent is used to derivatise polar analytes prior to gas-chromatographic separation, helping improve volatility and peak behaviour in routine GC workflows. This configuration provides 20 × 1 mL units, allowing portioned handling and reduced open-container exposure compared with bulk bottles. The product comes from manufacturer Macherey-Nagel and is listed among chromatography accessories for professional laboratory use. Transport is noted as ADR/IATA de minimis exempt under the stated packing. Classification includes signal word Warning together with H226, H315 and H319, indicating a flammable liquid that may cause skin and serious eye irritation; standard laboratory controls for ignition sources, gloves and eye protection apply. Net weight is 0,14 kg. The material is non-sterile and intended solely as a chemical reagent for analytical and research environments. Ideal where small, discrete silylation aliquots support method development, calibration series or day-to-day GC derivatisation tasks.
This article is part of Chromatography standards (GC, HPLC, pesticides), in Analytical standards & reference materials.

Questions about Silyl-991, 20x1 mL
What is this article?
Silyl-991, 20x1 mL is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in Chromatography standards (GC, HPLC, pesticides), inside Analytical standards & reference materials, in Lab chemicals.
A chromatography standard is the substance, or the mix, injected so a peak can be named and quantified. Pesticide mixes, residual-solvent mixes and single-compound standards are different articles. The concentration and the solvent are the specification. The solvent has to be one the method may contain.
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.
