Original design that provides a new way for fast and intuitive input of chemical formula with automated calculation of molecular weight by IUPAC data for elements.
Builtin online dictionary of compounds allows to lookup widespread compounds with they credentials: CAS, InChI, PubChem Id, names.
Main features:
input element in single touch
creating formula with indexes and charges
multileveled grouping, e.g. for K4[Fe(CN)]6
"dot-joined" syntax support: K2SO4·KHSO4·2.15KHSO5
formula for minerals support: (Mg,Fe2)5Si8O22(OH)2
calculation of molecular weight by IUPAC weights data
molecular weight calculation report
name, CAS #, PubChem ID, InChI credentials is accessible when online
