derivatization AmE

These employ a variety of extraction procedures followed by derivatisation to their trimethylsilyl derivatives.

With stepwise derivatisation, especially additions to the double bond present in some of the terpenes, he achieved the goal of obtaining crystalline compounds.

The technique has benefits over LC-FLD as the derivatisation and purification extraction steps are not necessary.

The main derivatisation routes include hydrolysis, fractional solvent crystallisation, esterification, hydrogenation, and alkoxylation and quaternisation.

Bis(trimethylsilyl)acetamide (BSA) is used in analytical chemistry for the derivatisation of compounds in analysis to increase their volatility.

The gelatinization temperature of starch depends upon plant type and the amount of water present, pH, types and concentration of salt, sugar, fat and protein in the recipe, as well as derivatisation technology used.

Despite its potent antitumor potential, geldanamycin presents several major drawbacks as a drug candidate (namely, hepatotoxicity) that have led to the development of geldanamycin analogues, in particular analogues containing a derivatisation at the 17 position:

To this end it is prudent to perform total homocyst(e)ine analysis in which all disulphide bonds are subject to reduction prior to analysis, traditionally by HPLC after derivatisation with a fluorescent agent, thus giving a true reflection of the quantity of homocysteine in a plasma sample.

There is no derivatization and little if any sample preparation.

The main difference is that chemical derivatization is not necessary.

This is done conveniently by derivatization of the temperature curve.

Another example is found in the derivatization of cyclen.

A derivate is the product of a derivatization reaction.

It is a chemical for acetylation in the synthesis or derivatization of organic compounds.

Derivatization is possible by salt formation between an amine and a carboxylic acid.

The peptide length is limited due to the cyclical derivatization not always going to completion.

The derivatization of this compound class utilized standard procedures, the details of which will be published elsewhere.

Neutravidin still has lysine residues that remain available for derivatization or conjugation.

Derivatization of amino acids is necessary to ease its partition into a C18 bonded phase.

CDA must not racemize under derivatization or analysis conditions.

Several characteristics are desirable for a derivatization reaction:

The chemical reactivity of the alcohol group also allows chemical derivatization that is not possible with most other seed oils.

Quantitative data can be acquired, and good results of derivatization inside the PTV injector are published as well.

Reduce derivatives - Unnecessary derivatization (blocking group, protection/ deprotection, temporary modification) should be avoided whenever possible.

The derivatization problem can be resolved by cleaving large peptides into smaller peptides before proceeding with the reaction.

The electrochemical behavior of nabumetone by a voltammetric technique and a novel colorimetric method based on chemical derivatization were also published.

Crystals of different hydrazones have characteristic melting and boiling points, allowing the identity of a substance to be determined in a method known as derivatization.

Some examples of good derivatization reactions are the formation of esters and amides via acyl chlorides.

If such a derivatization reaction is available, the selectivity of APLI can be broadened to other molecule classes.

Dimethyl acetals (DMA) formed during derivatization are considered to be biomarkers of anaerobic bacteria.

Derivatization is a technique used in chemistry which transforms a chemical compound into a product (the reaction's derivate) of similar chemical structure, called a derivative.

The drawback to using MS techniques is that for gas chromatography, the sample must be prepared by chemical derivatization in order to obtain molecules with charge.

Neutral metal carbonyls can be converted to charged species by derivatization, which enables the use of electrospray ionization, instrumentation for which is often widely available.
