Thiodiglycolic Acid CAS 123-93-3

1. Thiodiglycolic acid is employed as an intermediate in the production of [1,4]oxathiane-2,6-dione by heating and is used as an antioxidant and reducing agent in the cosmetics industry . It also serves as a key intermediate in various organic syntheses for pharmaceuticals and agrochemicals .
2. The compound is used in analytical chemistry for the detection of heavy metals such as copper, lead, mercury, and silver due to its chelating properties . Thiodiglycolic acid CAS 123-93-3 is also a significant metabolite found in human urine following exposure to compounds like vinyl chloride monomer and the anti-cancer drug ifosfamide .
3. Applications of Thiodiglycolic acid include its use as a versatile building block in biochemical research and as a reagent capable of forming disulfide bonds, which is significant in various biochemical processes .

1. Store Thiodiglycolic acid in a tightly sealed container in a cool, dry, and well-ventilated condition, away from strong oxidizing agents and strong bases . Recommended storage is at ambient room temperature, protected from light and heat .
2. Keep Thiodiglycolic acid away from strong oxidizers, strong acids, and bases due to its incompatibility and to prevent hazardous decomposition .
3. Always use Thiodiglycolic acid CAS 123-93-3 appropriate personal protective equipment (PPE) including chemical-resistant gloves, protective clothing, and eye/face protection when handling Thiodiglycolic acid to avoid skin, eye, and respiratory contact .

1. Immediately isolate Thiodiglycolic acid CAS 123-93-3 the spill area and ensure adequate ventilation; contain Thiodiglycolic acid using inert, non-combustible absorbent material (e.g., sand) and prevent entry into drains or waterways .
2. Carefully sweep up the spilled Thiodiglycolic acid into a sealed, labeled chemical waste container for proper disposal according to local, state, and federal environmental regulations .
3. Personnel must wear suitable PPE during cleanup; Thiodiglycolic acid is classified for transport by some suppliers (UN3261, Hazard Class 8) and requires hazardous waste disposal .

1. Thiodiglycolic acid is classified with GHS signal word "Warning" or "Danger" . It causes skin irritation (H315), serious eye irritation (H319), and may cause respiratory irritation (H335) . Thiodiglycolic acid CAS 123-93-3 is also corrosive and can cause severe skin burns and eye damage (H314/H318) according to some classifications .
2. Thiodiglycolic acid is combustible and its thermal decomposition or combustion produces toxic and irritating fumes including carbon oxides and sulfur oxides . Thiodiglycolic acid CAS 123-93-3 has an oral LD50 (rat) of approximately 200-2000 mg/kg and is considered a corrosive substance that can cause injury to the skin, eyes, and respiratory tract .
3. Always consult the specific Safety Data Sheet (SDS) for Thiodiglycolic acid for complete hazard information, first-aid procedures (P305+P351+P338 for eyes, P302+P352 for skin), and handling instructions; precautionary statements include P280 (wear protective gloves/eye protection) .
