Application
1. Methoxyacetic anhydride is primarily used as a key intermediate in the synthesis of the pharmaceutical decitabine (5-Aza-2'-deoxycytidine), a drug for treating leukemia .
2. Methoxyacetic anhydride CAS 19500-95-9 serves as a versatile acylating agent in organic synthesis to introduce the methoxyacetyl group into various compounds for producing pharmaceuticals, agrochemicals, and other specialty chemicals .
3. Applications of Methoxyacetic anhydride also include its use in esterification and acylation reactions as an acyl donor, where its metabolite methoxyacetic acid has been studied for histone deacetylase (HDAC) inhibition in cancer and teratogenicity research .
Storage and Precautions
1. Store Methoxyacetic anhydride in a tightly sealed container under inert gas (e.g., nitrogen) in a cool, dry place, ideally at -20°C or refrigerated (2-8°C), and strictly protected from moisture .
2. Keep Methoxyacetic anhydride away from strong oxidizing agents, bases, and reducing agents due to incompatibility and potential violent reactions; avoid exposure to light for long-term integrity .
3. Always use Methoxyacetic anhydride CAS 19500-95-9 appropriate personal protective equipment (PPE) including chemical-resistant gloves, safety goggles, and protective clothing when handling Methoxyacetic anhydride to avoid contact with this moisture-sensitive and corrosive liquid .
Emergency response to leakage
1. Immediately isolate the spill area, ensure adequate ventilation, and contain Methoxyacetic anhydride using inert, non-combustible absorbent material; prevent entry into drains or waterways .
2. Carefully collect Methoxyacetic anhydride CAS 19500-95-9 using non-sparking tools and place it into a sealed, labeled corrosion-resistant chemical waste container for proper disposal according to local, state, and federal environmental regulations .
3. Personnel must wear suitable PPE including chemical-protective clothing and self-contained breathing apparatus (SCBA) during cleanup; Methoxyacetic anhydride is classified for transport (UN3265, Hazard Class 8, PG III) as a corrosive liquid .
Safety Information
1. Methoxyacetic anhydride is classified as a corrosive substance (GHS05, Danger) causing severe skin burns and serious eye damage (H314/H318) .
2. Methoxyacetic anhydride is moisture sensitive, very soluble in water (193 g/L at 25°C), and reacts with water to form methoxyacetic acid; its thermal decomposition produces toxic and irritating fumes including carbon oxides .
3. Always consult Methoxyacetic anhydride CAS 19500-95-9 the specific Safety Data Sheet (SDS) for Methoxyacetic anhydride for complete hazard information, first-aid procedures (P305+P351+P338 for eyes, P301+P330+P331 for ingestion, P303+P361+P353 for skin), and handling instructions; precautionary statements include P260 (do not breathe vapors), P280 (wear protective gloves/eye protection), and P405 (store locked up) .
