Monona,
I read your E-mail inquiry regarding various allotropes of phosphorous
and immediately opened my Merck Index. According to the Merck, t
here is only one CAS number for phosphorous [7723-14-0]. They do no
t provide individual CAS numbers for the different allotropes. It a
lso states that there are three main allotropic forms: white, black and r
ed. White is sometimes refered to as yellow as a result of impuriti
es, while red is sometimes refered to as violet. I also checked t
he CRC Handbook of Chemistry and Physics just for confirmation.
; The Merck Index provides some health and safety information.
