"derivatisation reagent"

Supplier: Thermo Fisher Scientific

Phenylisothiocyanate (PITC) is a high-purity reagent for pre-column quantitative derivatisation of amino acids by reverse-phase HPLC.

Supplier: Thermo Fisher Scientific

Fluoraldehyde crystals are o-phthalaldehyde (OPA), a highly sensitive fluorescent derivatisation reagent for peptide or amino acid detection and quantitation in HPLC.

TMCS is often used as a catalyst with other trimethylsilyl reagents. Without additives it can be used for preparing TMS derivatives of organic acids. Together with methanol it can be used for methylation.

TSIM is the strongest hydroxyl silylator; reagent of choice for carbohydrates and most steroids (even highly hindered steroids).

Supplier: Apollo Scientific

Reagent for derivatisation of amines, alcohols etc, for GC purposes.

Supplier: MACHEREY-NAGEL

Acylation with fluorinated acid anhydrides can be used for alcohols, phenols, carboxylic acids, amines, amino acids and steroids forming volatile, stable derivatives suited for FID as well as for ECD detection.

Supplier: Apollo Scientific

Reagent for the derivatisation of amines and alcohols for GC analysis.

Supplier: MACHEREY-NAGEL

Acylation with HFBA can be used for alcohols, phenols, carboxylic acids, amines, amino acids and steroids forming volatile, stable derivatives suited for GC-FID as well as for GC-ECD detection.

Supplier: MACHEREY-NAGEL

This derivitisation reagent is recommended for alcohols, primary and secondary amines as well as for thiols under mild, neutral conditions. MBTFA also forms very volatile derivatives with carbohydrates.

Supplier: Apollo Scientific

Derivatising agent for GC; Superior reagent in quantitation of Amphetamine & Methamphetamine in urine by GC/MS.

Supplier: MACHEREY-NAGEL

Silylation reagent with recommended applications: carboxylic acids, alcohols, phenols, primary and secondary amines and amino acids.

Supplier: MACHEREY-NAGEL

Silylation in GC stands for replacement of active hydrogen atoms by a trimethylsilyl group (TMS derivative).

Supplier: MACHEREY-NAGEL

HMDS is weak TMS donor. If used as sole reagent, it is slow and not very effective. After addition of catalytic quantities (e.g., 1 %) of TMCS or as a mixture with TMCS it is a fast and quantitative reagent for trimethylsilylation of organic compounds.
