[Chemical Properties]

White powder.Insoluble in water; soluble in alcohol.
[Application]

Xanthydrol may be used as a derivatization agent for the following:
Analysis of urea in urine and wine samples using high-performance liquid chromatography (HPLC) technique.
Analysis of trace levels of carbamate pesticides in surface water by gas chromatography–mass spectrometry (GC-MS).
[Uses]

Intermediate in the preparation of Propantheline Bromide.
[Preparation]

synthesis of xanthydrol: The amalgam sodium in dry toluene was warmed to 50°C, the xanthone-ethanol suspension was added, and the temperature was rapidly raised to 60-70°C with vigorous stirring. After the reaction is completed, the mercury is separated. The reaction solution was filtered, the filtrate was poured into the stirred blue distilled water, the 9-hydroxyxanthene was filtered out, washed with water, and dried to obtain the finished product with a yield of 91-95%.
[Reactions]

9-Hydroxyxanthene (xanthydrol) reacts with a variety of proteins and inactivates certain enzymes. The research data indicate that in acetic acid solution xanthydrol reacts with the following amino acids: arginine, asparagine, cysteine, glutamine, histidine, lysine, and tryptophan. The a-amino group of cu-amino acids does not react with xanthydrol under these conditions, since alanine, serine, isoleucinc, and tyrosine failed to react[1].
[General Description]

Xanthydrol is also known as 9H-xanthen-9-ol.
[Purification Methods]

Crystallise xanthydrol from EtOH and dry it at 40-50o. [Beilstein 17 H 129, 17 I 72, 17 II 146, 17 III/IV 1602, 17/4 V 502.]
