ITEM #: 13364106
Purpose of derivatization
  • Improved volatility, better thermal stability or a lower limit of detection in GC
  • Prerequisite: quantitative, rapid and reproducible formation of only one derivative
  • Halogen atoms introduced by derivatization (e.g., trifluoroacetates) for specific detection (ECD) with the advantage of high sensitivity
  • Influence of elution orders and fragmentation patterns in MS by a specific derivatization

Silylation reagent BSA
  • Strong...

  • Influence of elution orders and fragmentation patterns in MS by a specific derivatization

Silylation reagent BSA
  • Strong silylation reagent, which forms very stable TMS derivatives of a wide variety of compounds, e.g., alcohols, amines, carbo x ylic acids, phenols, steroids, biogenic amines and alkaloids
  • Not Recommended for use with carbohydrates or very low molecular weight compounds
  • Good solvent for polar compounds, but frequently used in combination with a solvent (pyridine, DMF etc.) or with other silylation reagents
  • When used with DMF, BSA is the reagent of choice for derivatizing phenols

Silylation reagent BSTFA
  • Powerful trimethylsilyl donor with appro x imately the same donor strength as the nonfluorinated analog BSA
  • Advantage of BSTFA over BSA: greater volatility of its reaction products (particularly useful for GC of some lower boiling TMS amino acids)
  • BSTFA is nonpolar (less polar than MSTFA), and can be mi x ed with acetonitrile for improved solubility.
  • For silylating fatty acid amides, hindered hydro x yls and other compounds, which are difficult to silylate (like secondary alcohols and amines), we recommend BSTFA + 1 % trimethylchlorosilane (TMCS), available under the designation SILYL-991.

These products can contain harmful substances which must be specially labeled as hazardous.
