Abstract
Typical urinary phenols and oestrogens have been converted into azo dyes by coupling with diazotized I.C.I. M5091.
The dyes have been characterized from the following data:
(a) partition properties;
(b) solubility properties in a phosphate buffer;
(c) adsorption properties;
(d) absorption spectra data 310–600 mμ.
Decalso, after treatment with barium acetate solution, has been introduced as a new adsorbent in chromatography.
The removal of indigoid pigments from urinary oestriol fractions by a new procedure is described.
The addition of thiourea and benzene to urines during acid hydrolysis affords some protection to oestradiol-3:17α.
