DL-Tartaric Acid CAS 133-37-9

1. DL-Tartaric acid is widely utilized as an acidulant and flavor enhancer in the food industry, providing a sour taste in beverages, candies, and baked goods .
2. DL-Tartaric acid CAS 133-37-9 serves as a pharmaceutical intermediate and chiral resolving agent in drug synthesis, and is used to prepare medicinal compounds like antimony potassium tartrate .
3. DL-Tartaric acid functions as a complexing agent in electrosynthesis, a dopant in conducting polymer production, and a raw material for manufacturing tartrate salts and esters .

1. Store DL-Tartaric acid in a tightly sealed container in a cool, dry, well-ventilated area, protected from light and moisture, with recommended storage at -20°C for long-term stability .
2. Keep DL-Tartaric acid CAS 133-37-9 strictly away from strong oxidizing agents, strong bases, fluorine, and hydrogen peroxide due to incompatibility and potential hazardous reactions .
3. Handle DL-Tartaric acid using appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and a NIOSH/MSHA-approved respirator, and avoid breathing dust .

1. Isolate the spill area, wear full protective equipment including self-contained breathing apparatus, and avoid dust generation when handling solid DL-Tartaric acid .
2. Sweep up spilled DL-Tartaric acid CAS 133-37-9 into sealed, labeled containers for disposal; for solutions, absorb with liquid-binding material like diatomite and decontaminate surfaces with alcohol .
3. Prevent spilled DL-Tartaric acid from entering drains or waterways, and dispose of waste according to local, state, and federal environmental regulations .

1. DL-Tartaric acid is an irritant, causing skin irritation (H315), serious eye damage (H318), and respiratory irritation (H335), with GHS signal word "Danger" according to ILO .
2. DL-Tartaric acid CAS 133-37-9 is a combustible solid (flash point 210°C, auto-ignition 425°C); thermal decomposition produces toxic fumes including carbon monoxide, carbon dioxide, and nitrogen oxides .
3. DL-Tartaric acid has an oral LD50 > 2000 mg/kg in rats, MAK of 2 mg/m³, and is considered non-hazardous for transport by most regulations (UN Classification: none) .
