Reagents for Organic Chemistry

Wet-chemical reagents for organic analysis work by converting an analyte into something visible or measurable. Colorimetric reagents form a coloured product whose intensity relates to concentration — o-tolidine develops yellow with free chlorine and was for decades the standard field test for residual chlorine in water. Molychem supplies reagents for organic chemistry including Chlorotex reagent, o-tolidine for chlorine estimation and Chromotrope 2B in laboratory packs.
