2-Mercaptopropionic Acid CAS 79-42-5

1. 2-Mercaptopropionic acid is a key pharmaceutical intermediate used in the synthesis of drugs such as fennerol and in overcoming chemoresistance in melanoma by inhibiting PCK1 .
2. 2-Mercaptopropionic acid CAS 79-42-5 serves as an essential coating agent for silver sulfide (Ag2S) quantum dots, enabling their use as stable, luminescent probes in bioimaging and drug delivery systems .
3. 2-Mercaptopropionic acid is employed as a biochemical reagent in high-speed amino acid analysis and as a phenotypic test reagent for detecting metallo-β-lactamase (MBL)-producing bacteria .

1. Store 2-Mercaptopropionic acid in a tightly sealed container under inert gas at refrigerated temperatures (2-8°C), as it is sensitive to air, light, and moisture and decomposes upon exposure .
2. Keep 2-Mercaptopropionic acid CAS 79-42-5 strictly away from strong oxidizing agents, strong bases, and strong reducing agents, and protect from heat and ignition sources due to its combustibility (flash point 88-112°C) .
3. Handle 2-Mercaptopropionic acid using appropriate personal protective equipment including chemical-resistant gloves (butyl-rubber), tightly fitting safety goggles with face shield, and in a fume hood to avoid breathing vapors and contact with skin and eyes .

1. Isolate the spill area, eliminate all ignition sources, and ensure adequate ventilation; wear full protective equipment including self-contained breathing apparatus before handling 2-Mercaptopropionic acid .
2. Contain liquid 2-Mercaptopropionic acid CAS 79-42-5 using dry inert absorbent material like sand, collect using non-sparking tools into sealed, labeled containers, and prevent entry into drains or waterways .
3. Personnel cleaning 2-Mercaptopropionic acid spills must dispose of waste through licensed chemical destruction or controlled incineration with flue gas scrubbing, as 2-Mercaptopropionic acid is classified for transport as a toxic liquid (UN 2936, Hazard Class 6.1, PG II) .

1. 2-Mercaptopropionic acid is classified with GHS signal word "Danger" as a corrosive and toxic substance (H314, H318, H301), causing severe skin burns, serious eye damage, and is toxic if swallowed (oral LD50 rat: 244 mg/kg; rabbit: 730 mg/kg) .
2. 2-Mercaptopropionic acid CAS 79-42-5 is harmful if inhaled (H331, toxic by inhalation), causes skin sensitization (H317, may cause allergic skin reaction), and is combustible (flash point 88-112°C) .
3. 2-Mercaptopropionic acid has a melting point of 10-14°C, boiling point of 203-208°C (lit.), density of 1.196 g/mL, is miscible with water, alcohol, and ether, and thermal decomposition produces toxic fumes including carbon oxides and sulfur oxides .
