 - When element symbols are used with a type of reaction as a noun or adjective, use normal type for the symbol and hyphenate it to the word that follows it. N-acetylated, N-acetylation, N-oxidation, N-oxidized, O-substituted, O-substitution.
 - Use italic type for the capital H that denotes indicated or added hydrogen. 1<i>H</i>-1,3-diazepine, 3<i>H</i>-fluorene 2H-indene
 - Use Greek letters, not the spelled-out forms, in chemical names to denote position or stereochemistry. Use a hyphen to separate them from the chemical name. α-amino acid (not alpha amino acid), β-naphthol (not beta naphthol).
-- Use italic type for positional, stereochemical, configurational, and descriptive structural prefixes when they appear with the chemical name or formula. Use a hyphen to separate them from the chemical name. Examples: abeo, ac, altro, amphi, anti, antiprismo, ar, arachno, as, asym, c, catena, cis, cisoid, closo, cyclo, d, dodecahedro, E, endo, erythro, exo, facgem, hexahedro, hexaprismo, hypho, icosahedro, klado, l, m, M, mer, meso, n, nido, o, octahedro, p, P, pentaprismo, quadro, r, R, R∗, rel, retro, ribo, s, S, S∗, sec, sn, sym, syn, t, tert, tetrahedro, threo, trans, transoid, triangulo, triprismo, uns, vic, xylo, Z.

 - Do not capitalize prefixes that are shown here as lowercase, even at the beginning of a sentence or in a title and never use lower case for those that are written in capital letters. Enclose the prefixes E, R, R∗, S, S∗, and Z in parentheses. <i>anti</i>-bicyclo[3.2.1]octan-8-amine, <i>ar</i>-chlorotoluene, <i>cis</i>-diamminedichloroplatinum, <i>cyclo</i>-hexasulfur, c-S6; (<i>E,E</i>)-2,4-hexadienoic acid; <i>m</i>-ethylpropylbenzene; <i>o</i>-dibromobenzene, <i>p</i>-aminoacetanilide; (<i>S</i>)-2,3-dihydroxypropanoic acid; 5-<i>sec</i>-butylnonane.
 - Multiplying affixes are integral parts of the chemical name; they are set in normal type and are always closed up to the rest of the name (without hyphens). Use hyphens only to set off intervening locants or descriptors. Use enclosing marks (parentheses, brackets, or braces) to ensure clarity or to observe other recommended nomenclature conventions. Multiplying prefixes include the following: 
 - hemi, mono, di, tri, tetra, penta, hexa, hepta, octa, ennea, nona, deca, deka, undeca, dodeca, etc.
