Hyphosphorus acid is acclimated in the conception
of pharmaceuticals, birthmark of polymers, baptize treatment, retrieval of
adored or non-ferrous metals. Its capital use is for electroless plating; i.e.
degradation of baddest metal films from band-aid on a sensitized surface. In
amoebic chemistry, H3PO2 best accepted for their use in the abridgement of
arenediazonium salts, converting ArN2+ to Ar-H. When diazotized in a
concentrated band-aid of hypophosphorous acid, an amine substituent can be
removed from arenes, selectively over alkyl amines.
DEA List I actinic status
Because Hyphosphorus acid can abate basal iodine to
anatomy hydroiodic acid, which is a reagent able for abbreviation ephedrine or
pseudoephedrine to methamphetamine, the United States Drug Enforcement
Administration appointed hypophosphorous acerbic (and its salts) as a List I
forerunner actinic able November 16, 2001. Accordingly, handlers of
hypophosphorous acerbic or its salts in the United States are accountable to
acrimonious authoritative controls including registration, recordkeeping,
reporting, and import/export requirements pursuant to the Controlled Substances
Act and 21 CFR §§ 1309 and 1310.
Inorganic and amoebic derivatives
Numerous derivatives are accepted in which the two
hydrogen atoms anon apprenticed to phosphorus are replaced by amoebic groups.
These derivatives are accepted as phosphinic acids, and their salts as
phosphinates. For example, formaldehyde and H3PO2 acknowledge to accord
(HOCH2)2PO2H. The acknowledgment is affiliated to the accession of thiols and
HCN to aldehydes. Similarly, it adds to Michael acceptors, for archetype with
acrylamide it gives H(HO)P(O)CH2CH2C (O)NH2.
Few metal complexes accept been able from H3PO2, one
archetype is Ni(O2PH2)2.
