Application:
Cyclopropylacetylene (CAS: 6746-94-7) is used as an organic chemical synthesis intermediate. Cyclopropylacetylene is a key intermediate of Efavirenz (CAS: 154598-52-4). Efavirenz [brand names Sustiva® and Stocrin®] is a kind of non-nucleoside reverse transcriptase inhibitor (NNRTI) and can be used as part of highly active antiretroviral therapy (HAART) for the treatment of a human immunodeficiency virus (HIV) type 1. For HIV infection that has not previously been treated, Efavirenz and Lamivudine in combination with Zidovudine or Tenofovir is the preferred NNRTI-based regimen. Efavirenz can also be used in combination with other antiretroviral agents as part of an expanded postexposure prophylaxis regimen to prevent HIV transmission for those exposed to materials associated with a high risk for HIV transmission.Sufficient Capacity: Sufficient facilities and technicians
