Methyl orange is an orange, azoic dye. It has a transition range from 3.1 to 4.4. Methyl orange does not have a full spectrum of color change, but has a sharper end point. Methyl orange shows red color in acidic medium (pH < 3.1) and yellow color in basic medium (pH > 4.4). It...
This present work aims to investigate the influence of organic dyes (methyl orange (MO), hexamethyl pararosaniline chloride (HPC)) doped with potassium hydrogen phthalate ammonium sulfate (KHPA) crystals. The solution-grown dye doped KHPA were examined using powder-XRD, FT-IR, UV鈥搗isible ...
The sodium hydrogen sulfite was added little by little until the orange color of chromium (VI) disappeared. The liquid was then separated and the bottom layer was extracted with petroleum ether (1,000 ml). Since the liquid was again separated into two layers when the extract was combined ...

a DNA methylation of 174 (including 74 matched tumor and non-tumor samples) bladder cancer specimens distinguished between tumor (orange) and non-tumor tissue (yellow). Red color indicates hypermethylation and green color indicates hypomethylation. Each row is a CG site, and each column is a dif...
The crude product was purified by careful silica gel chromatography (eluted with hexanes/ethyl acetate 8:2) to furnish an orange oil which solidified on standing. This was recrystallized from dichloromethane/hexanes to furnish the desired product as a pale yellow solid (4.4 g, 32%); 1 H NMR...
