Reactive Yellow 2 or Reactive Brilliant Yellow K-6G, is a water-soluble, monochlorotriazine-based reactive dye featuring an azo chromophore and sulfonate groups for enhanced solubility, applied under alkaline conditions where the reactive chlorine atom undergoes nucleophilic substitution with hydroxyl groups on fabrics like cotton to form permanent bonds; it provides vibrant yellow hues with good fastness but can contribute to wastewater pollution due to its recalcitrant nature, necessitating advanced treatment methods such as adsorption for removal.<\/p>\n<h3>Specification<\/h3>\n<table>\n<tbody>\n<tr>\n<td width=\"50%\">Item<\/td>\n<td width=\"50%\">Value<\/td>\n<\/tr>\n<tr>\n<td width=\"50%\">Melting Point<\/td>\n<td width=\"50%\">&gt;300\u00b0C<\/td>\n<\/tr>\n<tr>\n<td width=\"50%\">Boiling Point<\/td>\n<td width=\"50%\">1261.18\u2103[at 101 325 Pa]<\/td>\n<\/tr>\n<tr>\n<td width=\"50%\">Density<\/td>\n<td width=\"50%\">1.93[at 20\u2103]<\/td>\n<\/tr>\n<tr>\n<td width=\"50%\">Color<\/td>\n<td width=\"50%\">Gold-orange to orange-brown<\/td>\n<\/tr>\n<tr>\n<td width=\"50%\">Form<\/td>\n<td width=\"50%\">Powder<\/td>\n<\/tr>\n<tr>\n<td width=\"50%\">Storage Temp.<\/td>\n<td width=\"50%\">Refrigerator, Under inert atmosphere<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h3>Feature<\/h3>\n<ul>\n<li><b>Physical Properties<\/b>: Gold-orange to orange-brown solid powder with a molecular weight of 831.02 g\/mol, high water solubility (approximately 2.87 mg\/L at 25\u00b0C), density of 1.93 g\/cm\u00b3, and a maximum absorption wavelength around 404 nm; exhibits low volatility and a melting point exceeding 300\u00b0C.<\/li>\n<li><b>Chemical Reactivity<\/b>: Contains a monochlorotriazine reactive group for covalent attachment under neutral to mildly alkaline conditions (pH 7-9), stable in neutral media but hydrolyzes in strong bases or acids; the azo linkage provides intense yellow coloration, with incompatibility toward strong oxidants or reducing agents.<\/li>\n<li><b>Synthesis<\/b>: Produced via diazotization of a substituted aniline derivative followed by coupling with a pyrazolone component and subsequent attachment to cyanuric chloride, yielding a technical-grade product with purity typically 50-60% in commercial formulations.<\/li>\n<li><b>Safety Profile<\/b>: May cause skin, eye, or respiratory irritation upon contact or inhalation;
