Disease relevance of ammonium fluoride hydrofluoride

Ammonium fluoride pustulation was not reproducible; croton oil pustules were more difficult to evaluate due to simultaneous erythema and edema [1].

High impact information on ammonium fluoride hydrofluoride

Fused silica capillaries for use in electrophoretic analyses are etched with ammonium bifluoride in the presence of a second inorganic salt (CuCl(2), CrCl(3), NaNO(3), or (NH(4))(2)CO(3)) [2].
These are the first pediatric reports of near-fatal outcomes after ingestion or inhalation of a hydrofluoric acid-like product, namely, ammonium bifluoride [3].
Innocuity of tetradecyl-dimethyl-benzyl ammonium fluoride on the DNA of human spermatozoa [4].
Stepwise removal of the silyl protecting group starting with tetrabutyl ammonium fluoride followed by use of the HF/pyridine complex suppressed a possible rearrangement of the aglycon and successfully terminated the sequence [5].
The method entails extraction of beryllium workplace samples by 1% ammonium bifluoride (NH(4)HF(2), aqueous), followed by fluorescence detection using hydroxybenzoquinoline sulfonate (HBQS) [6].

Anatomical context of ammonium fluoride hydrofluoride

The inner walls of 50 microns fused-silica capillaries are etched by ammonium hydrogendifluoride and then modified by the silanization/hydrosilation method with a chiral selector [7].
Porcelain disks (VMK 68 dentin) were either air abraded with alumina (AAA) or etched with one of the following five etchants: (1) ammonium hydrogen bifluoride (AHB); (2) acidulated phosphate fluoride (APF); (3) hydrofluoric acid (HFA); (4) phosphoric acid (PHA); and (5) sulfuric acid-hydrofluoric acid (SHF) [8].

Associations of ammonium fluoride hydrofluoride with other chemical compounds

Mean values and 95% confidence intervals were (in degrees): control, 63.8 +/- 2.7; ammonium bifluoride, 39.4 +/- 2.0; airborne particle abrading, 29.1 +/- 2.9; acidulated phosphate fluoride, 24.9 +/- 1.7; and hydrofluoric acid, 16.5 +/- 1 [9].
Uptake of fluoride by human surface enamel from ammonium bifluoride and consequent reduction in the penetration in vitro by caries-like lesions [10].
Ultra-trace determination of beryllium in occupational hygiene samples by ammonium bifluoride extraction and fluorescence detection using hydroxybenzoquinoline sulfonate [6].

Analytical, diagnostic and therapeutic context of ammonium fluoride hydrofluoride

In the short-term study biopsies were obtained prior to and after treatment with acidic sodium or ammonium fluoride [11].
