Re. : IPC/WG/5/3 par. 23
Classification definitions for subclass C 07F
1. Title
ACYCLIC,
CARBOCYCLIC,
OR
HETEROCYCLIC
COMPOUNDS
CONTAINING ELEMENTS OTHER THAN CARBON, HYDROGEN,
HALOGEN, OXYGEN, NITROGEN, SULFUR, SELENIUM, OR TELLURIUM 
2. Definition statement
This subclass covers:
A.
Organic (acyclic, carbocyclic, heterocyclic) compounds containing
elements other than carbon, hydrogen, halogen, oxygen, nitrogen, sulfur,
selenium, or tellurium with or without them (e.g. metallo-organic
compounds,
boron
compounds,
silicon
compounds,
phosphorus
compounds, arsenic compounds).
B.
The preparation of compounds under the subclass definition including
purification, separation, stabilisation or use of additives (see Class C07, 1
note) unless provided for elsewhere, as specified below.
C.
The treatment and modification of compounds under the subclass
definition (except for mechanical treatment) provided that (1) the
treatment is not provided for elsewhere and (2) the resultant product is a
compound under the subclass definition.
3. Relationships between large subject matter areas
This subclass is a functional-oriented entry, thus, it does not cover the application or use of
the compounds under the subclass definition. For classifying such information other entries
in IPC exist, e.g:
A 01 N
PRESERVATION OF BODIES OF HUMANS OR ANIMALS OR PLANTS OR PARTS THEREOF;
BIOCIDES,
e.g.
AS
DISINFECTANTS,
AS
PESTICIDES,
AS
HERBICIDES
REPELLANTS OR ATTRACTANTS; PLANT GROWTH REGULATORS 
PEST

A 61 K
PREPARATIONS FOR MEDICAL, DENTAL, OR TOILET PURPOSES 

4. Limiting references
1. Products obtained from layered base-exchange silicates by ion-exchange with
organic compounds such as ammonium, phosphonium or sulfonium compounds or
by intercalation of organic compounds C01B 33/44.
2. Metal-containing porphyrins C07D 487/22.
3. Sugar phosphates C07H 11/04.
4. Nucleotides C07H 19/00, 21/00.
5. Nucleic acids C07H 21/00.
6. Macromolecular compounds C08.
7. Organic acid salts, alcoholates, phenates, chelates or mercaptides, having no
elements other than carbon, hydrogen, halogen, oxygen, nitrogen, sulfur, selenium,
or tellurium in the parent compounds C07C, C07D (attention is drawn to note 5
following the title of class C07 concerning the rules of classification of these
compouns).
8. Fermentation or enzyme-using processes to synthesise a desired chemical compound
or composition or to separate optical isomers from a racemic mixture C12P.
9. Production of organic compounds by electrolysis or electrophoresis C25B 3/00, 7/00
5. Informative references
1. Dyes C09.
2. Fermentation products C12.
6. Special rules of classification
1. The last place rule in whole Class C07 (See Class C07, 2 note) is also effective for
this subclass. According to it, e.g. sugar phosphates are classified in group C07H
11/04 as sugars and not in group C07F 9/00 as phosphorus compounds (See also
Limiting References 2, 3, 4) and peptides are classified in subclass C07K.
2. In this subclass, in the absence of an indication to the contrary, classification is made
in the last appropriate place, e.g. ferrocenes and cobaltocenes are classified in in
group C07F 17/00 and not in group C07F 15/00 (See Class C07, 2 note)
3. Metal compounds according to more than one of main groups C07F 1/00 – 17/00 are
classified in group C07F 19/00.
4. In this subclass, organic acid salts, alcoholates, phenates, chelates or mercaptides are
classified as the parent compounds (See subclass C07F, 3 note).
5. Salts, adducts or complexes formed between two or more organic compounds are
classified according to all compounds forming the salts, adducts or complexes (See
Class C07, 5 note).
6. Therapeutic activity of compounds is further classified in subclass A61P.
7. In this subclass it is desirable to add indexing codes of subclass C07M. The
indexing codes should be unlinked.
7. Glossary of terms
1. Metallocene – dicyclopentadienyl compound of transitional metal, e.g., ferrocenes.
2. Salt – product of substitution of hydrogen in carboxyl group of acid by ion of metal
or other cation.
3. Phenate – product of substitution of hydrogen in hydroxy group of phenol by metal
atom.
4. Alcoholate - product of substitution of hydrogen in hydroxy group of alcohole by
metal atom.
5. Chelate – intracomplex compound i.e. compound containing intramolecular donoracceptor bonds.
6. Metallo-organic compound – organic compound containing Me – C bond.
7. Organic compound – compound characterized by having (a) at least two carbon
atoms bonded together or (b) one carbon atom bonded to at least one atom of
hydrogen, halogen or nitrogen, except for hydrogen cyanide, cyanogen, cyanamide,
cyanogen halide, carbides, phosgene, thiophosgene, cyanic, thiocyanic, isocyanic,
isothiocyanic, carbamic acids.
