5-hydroxy-1-tetralone as the fluorescent labeling reagent.

1-Hydroxypyrene (1-Pyrenol), a biomarker of exposure to polycyclic aromatic hydrocarbons, is analyzed in urine samples.

Acetyl-L-lysine (Nα-Acetyl-L-lysine) is a N-acetylated amino acid. It is a normal constituent of human urine with concentrations in normal samples too small to allow its routine detection; however, it has been found at increased levels in the urine of a patient with aminoacylase I deficiency.

3-Furanoic acid (3-Carboxyfuran) is an organic acid regularly occurring in the urine of healthy individuals. 3-Furanoic acid (3-Carboxyfuran) is also a compound found in honey and honeydew samples.

Tetracontane is a long-chain saturated hydrocarbon primarily used as a non-polar solvent and as a calibration standard for determining hydrocarbons in soil samples.

Acid red 88 is an anionic dye with potentially useful photocatalytic research applications. Acid red 88 has been used to determine the effect of Au deposition on ZnO photocatalytic activity under visible light. Additionally, the photocatalyst Au-TiO2 was

Blood group A antigen tetraose type 5 (A-Tetrasaccharide), a tetrasaccharide specific to blood group A, inhibits the binding of anti-A antibody to blood group A substance and can be isolated from polar bear milk samples [1] [2].

Tetracontane (Standard) is the standard substance of Tetracontane, and it is applicable for quantitative analysis, quality control, and related research in biochemical experiments. Tetracontane is a long-chain saturated hydrocarbon primarily used as a non-polar solvent and as a calibration standard for determining hydrocarbons in soil samples.

Pollen extract, ragweed, is an allergen derived from ragweed samples and is utilized in allergenic research.

Pollen extract, timothy, is an allergen derived from timothy grass samples and is utilized in allergy research.

Methyl dotriacontanoate (C32:0 FAME; Lacceric acid methyl ester) is a naturally occurring fatty acid methyl ester found in the cuticular wax of P. abies needles. It is also present in sediment samples from the Suwannee River in Florida and Lake Kivu in the East African Rift.

Methyl (+/-)-2-hydroxytetracosanoate, a hydroxylated fatty acid methyl ester, occurs in both mature and immature strawberry homogenates, Pseudosuberites and S. massa sponges, sediment samples from the Hani River and Lake Kivu, and the aerial parts of Escherichia coli exposed to sunlight.

N-Cholyl-L-leucine is a bile acid amidate. It has been found in fecal samples from extremely premature infants with mild or severe brain injuries. N-Cholyl-L-leucine has been used as a standard for the detection of endogenous bile acid amidates in human plasma and fecal samples.

N-Cholyl-L-alanine is a bile acid amide identified in human fecal samples.
