| A metallized azo-ether dye comprising an azo group linking a substituted 3-hydroxy-pyridine nucleus to a phenyl nucleus wherein the phenyl nucleus has an alkoxy or thioether substituent at its 2-position. |
| In an interstitial solid solution, substituent atoms or ions are added to void spaces between normal atomic sites. |
| The various combinations of two fatty acids give rise to many different molecules bearing the same substituent group. |
| The amine is nearly planar owing to conjugation of the lone pair with the aryl substituent. |
| In one approach, cells are ground up and the substituent chemicals are fractionated for further analysis. |
| The highly electronegative fluorine substituent stabilizes this intermediate much more than do the other halogens and causes it to be formed faster. |
