3 5-Dinitrosalicylic Acid CAS 609-99-4

① Acts 3 5-Dinitrosalicylic acid as a colorimetric reagent for detecting reducing sugars in biochemical assays, such as glucose and maltose quantification in food and fermentation industries.
② Serves 3 5-Dinitrosalicylic acid CAS 609-99-4 as a key intermediate for synthesizing nitroaromatic compounds and pharmaceutical raw materials in fine chemical production.
③ Functions as a redox indicator in analytical chemistry, monitoring reaction progress in oxidation-reduction titration experiments.

Store at 0-10℃ in sealed amber glass/HDPE drums in cool, dry, dark area, away from open fire, strong oxidants, acids and direct sunlight. Wear nitrile gloves, safety goggles and dust mask; avoid inhalation, skin/eye contact & ingestion (irritant, toxic). Reseal tightly post-use to prevent photodegradation and caking. Dispose as hazardous waste; transport as non-hazardous solid, moisture-proof packaging, avoid mixing with oxidants and high-temp exposure.
