How should DL-Mandelic acid be handled and stored safely in a lab or factory?

Handle DL-Mandelic acid with gloves, safety glasses, and a lab coat since it's a mild irritant to skin and eyes. Weigh it in a fume hood to avoid inhaling dust-use a respirator if generating airborne particles. Dissolve in water or propylene glycol slowly while stirring to prevent clumping. Store in tightly sealed HDPE or glass containers under cool (15–25°C), dry, dark conditions-moisture can cause caking, and light may speed slight discoloration. (DL-Mandelic acid) keeps stable for 2–3 years when sealed properly; nitrogen purging extends shelf life for bulk drums. Label containers with batch number, purity, and hazard info. In case of skin contact, rinse with water for 15 minutes; seek medical help if irritation persists. Avoid mixing with strong oxidizers or bases that could trigger reactions. Spill cleanup uses absorbent pads and water rinse-dispose of waste per local chemical regulations. Proper handling prevents accidents and maintains product quality.
