“…Aldehydes are chemical species widely distributed in nature and they are identified in different matrices such as atmosphere [1][2][3][4], water [5] [6][7][8], and food [9,10] in the literature. Some short chain aldehydes are recognized to be irritants and allergens with toxic and carcinogenic properties [11].…”

“…In most cases, due to the physicochemical properties of this group of compounds, analytical procedures include derivatization step. Frequently used as a derivatization reagents are such derivatives of hydrazine as: 2,4-dinitrophenylhydrazine (DNPH) [5,12,17,21], 2,4,6-trichlorophenylhydrazine (TCPH) [20], 2,3,4,5,6-pentafl uorophenylhydrazine (PFPH) [14], 5-(dimethylamino)-naphthalene-1-sulfon-hydrazide (DNSH) [19], 3-methylbenzothiazole-2-hydrazine (MBTH) [11], 4-(N.N-dimethylaminosulfonyl)-7-N-methylhydrazino-2,1,3-benzoxadiazole (MDBDH) [9], 5-amino-4-sulfanylphthalhydrazide (ASPH) [8], hydroxylamine derivatives (O-benzylhydroxylamine (BOA) [10], o- (2,3,4,5,6-pentafl uorobenzyl)-hydroxylamine (PFBHA) [15], Hantzscha reagents (1,3-cykloheksadion (CHD), 5,5-dimethyl-1,3-cykloheksadion (Dimedon), 4-amino--3-penten-2-one (Fluoral P), acetylacetone, acetoacetanilid or 2-aminoethanethiol (cysteamine), 3-amonofl uoroethan [6,22]. DNPH is the commonly used derivatization agent for high performance liquid chromatography (HPLC), whereas PFBHA is usually used for gas chromatography.…”

Abstract:The paper presents two sample preparation procedures for the determination of aldehydes in wet deposition. In both cases the 2,4-dinitrophenylhydrazine derivatization and solid phase extraction were applied. The derivatization in method A was applied before the extraction, the extraction in method B was carried out with simultaneous derivatisation. Accuracy of both methods was evaluated on the basis of the analysis of aqueous solutions of selected carbonyl compounds. Both methods were characterized by good recovery, however, due to the precision of the method expressed as RSD for testing of environmental samples the method B was used.The analysis of environmental samples showed signifi cant differences in the concentrations of aldehydes in wet deposition, depending on the location of the sampling point. In the case of samples taken from agricultural areas the predominant aldehydes were formaldehyde and acetaldehyde. Formaldehyde was from 31% to 47% of the determined compounds. While in samples collected near a traffi c source, in the deposition acrolein was determined at the levels from 62% to 64% of the identifi ed compounds.

“…Both KG and HMF possess a carbonyl function that can be targeted as a reactive group for derivatization with reagents, such as dansylhydrazine (DNSH), a well-known fluorescence labelling reagent that can be monitored under UV detection as well. 22,23 Since ketones and aldehydes react differently, both reaction parameters, such as time, temperature and the reagent-substrate ratio, as well as chromatographic conditions and detection systems should be carefully investigated and combined together.…”

Simultaneous Quantitation of Alpha-ketoglutaric Acid and 5-Hydroxymethylfurfural in Plasma by HPLC with UV and Fluorescence Detection

Alpha-ketoglutaric acid (KG) and hydroxymethylfurfural (HMF) are currently being investigated in clinical trials as an approach in targeted cancer therapy. Hence, a method for the simultaneous determination of KG and HMF in plasma has been developed. Due to the strongly discriminative chemical properties of KG and HMF, SPE purification is performed using an ion-exchange cartridge to separate KG, and a hydrophobic polymeric cartridge to separate HMF. The cartridges are connected together for several steps, thus resulting in a quicker approach for the purification of plasma samples. The derivatization step is based on the reaction of the carbonyl groups of KG and HMF with dansylhydrazine (DNSH) catalyzed by trifluoroacetic acid. The formed derivatives could be separated by reversed-phase LC on a C8-column, and analyzed by UV and fluorescence detection in a single run using a gradient program. The obtained results show good reproducibility, specificity, and detection limits down to the low picomole range.
