1. 5-Methoxy-2,4-pyrimidinediol  must be stored in a tightly sealed container in a cool, dry, and well-ventilated environment; recommended storage at 2-8°C (refrigerated) or at room temperature in a cool, dark place below 15°C.
2. 5-Methoxy-2 4-pyrimidinediol is stable under recommended storage conditions and should be kept away from incompatible materials such as strong oxidizing agents, strong acids, and strong bases to prevent decomposition.
3. 5-Methoxy-2,4-pyrimidinediol is classified with GHS hazard statements H315 (Causes skin irritation), H319 (Causes serious eye irritation), with signal word "Warning".
4. Personnel must wear chemical-resistant gloves, safety goggles with side-shields, and protective clothing when handling this substance, ensuring adequate ventilation in work areas and avoiding formation of dust and aerosols.

1. Isolate the spill area, ensure adequate ventilation, and wear full personal protective equipment including chemical-resistant gloves, safety goggles, and suitable dust respirator when 5-Methoxy-2,4-pyrimidinediol is released.
2. Collect 5-Methoxy-2 4-pyrimidinediol by sweeping or vacuuming without creating dust using non-sparking tools, and place into suitable closed containers for disposal.
3. Avoid creating dust clouds during cleanup to prevent respiratory exposure; decontaminate surfaces and equipment by scrubbing with alcohol or appropriate methods.
4. Dispose of collected material according to local, state, and federal environmental regulations; the substance is considered non-hazardous for transport but requires proper waste management.

1. 5-Methoxy-2,4-pyrimidinediol CAS 6623-81-0 is not classified as highly flammable but may decompose under fire conditions, emitting toxic fumes including carbon monoxide, carbon dioxide, and nitrogen oxides.
2. Use water spray, dry chemical powder, carbon dioxide, or alcohol-resistant foam to extinguish fires involving the product; do NOT use a direct water jet as 5-Methoxy-2 4-pyrimidinediol may scatter burning material.
3. Firefighters should wear self-contained breathing apparatus in pressure-demand, MSHA/NIOSH approved, and full protective gear when handling burning 5-Methoxy-2,4-pyrimidinediol due to hazardous decomposition gases generated by thermal decomposition.
4. During combustion, may emit irritant and toxic fumes; contain fire runoff to prevent environmental contamination and pollution.
