It is also useful for the conversion of primary and secondary alcohols to alkyl bromides.Application: Phosphorus tribromide may be used as a reagent:. In a novel protocol for synthesizing 7-ethoxy-1-(p-ethylphenoxy)-3,7-dimethyl-2-octene, a synthetic juvenile hormone mimic of trans,trans,cis-10,11-epoxy-7-ethyl-3,11-dimethyltrideca-2,6-dienoate.. To synthesize 1,2,3-diazaphosphinane, 1,2,3-thiazaphosphinine and 1,2-azaphosphole bearing a chromone ring.RTECS: TH4460000RIDADR: UN 1808 8 / PGIIWGK Germany: 1R Codes: 14-34-37S Codes: 26-45IOD Codes: CSymbol: GHS05, GHS07Signal Word: DangerHazard Statements: H314-H335Precautionary statements: P261-P280-P301 P330 P331-P303 P361 P353-P304 P340 P310-P305 P351 P338
