Khoom Description
Cov tshuaj sib xyaw ua ke rau CAS 2082-59-9 yog Pentanoic Anhydride, nrog cov qauv molecular ntawm C10H18O3 thiab molecular hnyav ntawm 186.25 g / mol. Cov tshuaj yog tsim los ntawm lub cev qhuav dej ntawm ob valeric acid molecules. Nws yog xim tsis muaj xim rau lub teeb daj pob tshab kua nyob rau hauv chav tsev kub nrog ib tug pungent tsw.
Lub melting point ntawm Pentanoic Anhydride yog - 56 degree, lub boiling point yog 227-230 degree, qhov ceev yog 0.944 g / mL (20 degree), lub refractive index yog 1.421 (20 degree), thiab lub flash point yog 101℃(kaw khob). Nws yog soluble hauv cov kuab tshuaj organic xws li ethanol thiab ether, thiab maj mam hydrolyzes hauv dej los tsim valeric acid, uas yog acidic tsis muaj zog.

Siv
Hauv kev lag luam tshuaj: Pentanoic Anhydride yog cov khoom siv tseem ceeb rau butylphthalide (NBP), uas yog siv rau hauv kev kho mob ntawm ischemic stroke. Nws cov synthesis suav nrog esterification cov tshuaj tiv thaiv ntawm valeric anhydride thiab phthalide. Tsis tas li ntawd, nws tuaj yeem koom nrog hauv kev npaj cov tshuaj tiv thaiv kab mob, tshuaj tua kab mob thiab lwm yam tshuaj uas muaj carboxylic acid cov qauv.
Organic synthesis: Raws li tus neeg sawv cev acylating, nws yog siv rau hauv cov tshuaj tiv thaiv valerylation ntawm cawv thiab amines los npaj ester lossis amide compounds; Nws kuj tuaj yeem siv los ua cov khoom siv biodegradable, xws li valeryl esterified chitosan.
