Search common reagents by name, CAS, or formula for hazard summaries, handling controls, and incompatibilities. Each record links to its PubChem source and prompts a check of the current product SDS.

Reactive compounds and toxic gases may form. Never add bleach directly to guanidine-thiocyanate reagent or sample-preparation waste.
Collect separately, label clearly, and follow the product SDS and institutional hazardous-waste procedure.
Incompatible mixing can release hazardous gases; do not use bleach on chemically unidentified waste.
Stop mixing and follow the laboratory gas-release/spill procedure for evacuation and reporting.
Acids can generate hydrazoic acid and metals can form shock-sensitive azides; azide solutions must not be drain-disposed.
Use a dedicated compatible waste container and have EHS assess historical discharge or suspected deposits.
Concentrated hydrogen peroxide is a strong oxidizer; contamination can accelerate decomposition, heat and gas release, ignite combustibles, or overpressurize a closed vessel.
Never return excess reagent to the stock bottle; isolate a contaminated container and report under the product SDS and institutional oxidizer-spill procedure.
Nitric acid is both a strong acid and an oxidizer; contact with organics, reducing agents, or unidentified waste can cause violent heat release and toxic gases.
Use a dedicated compatible oxidizing-acid waste container segregated from organic waste; after accidental mixing, stop work, evacuate, and activate EHS response.
A common buffer, electrolyte, and culture-medium component; most classifications aggregated by PubChem do not classify it as GHS hazardous, while dust and concentrated solutions still require routine controls.
This source does not provide one set of H-codes that applies to every form or concentration. Open the source and check the current product SDS.
Strong oxidizers; mixture compatibility depends on the other components.
Low intrinsic hazard does not remove the biological effects of concentrated electrolyte or cover additives and biological contaminants.
