How to dispose of expired vitamins “It’s recommended to mix supplements with dry matter like dirt, coffee grounds, or something else that would prevent someone from eating it. Then, bag it up ...
Tetrahydrofuran (THF), or oxolane, is an organic compound with the formula (CH 2) 4 O. The compound is classified as heterocyclic compound , specifically a cyclic ether . It is a colorless, water- miscible organic liquid with low viscosity .
Drug disposal is the discarding of drugs. Individuals commonly dispose of unused drugs that remain after the end of medical treatment. [1] Health care organizations dispose of drugs on a larger scale for a range of reasons, including having leftover drugs after treating patients and discarding of expired drugs.
Borane–tetrahydrofuran is an adduct derived from borane and tetrahydrofuran (THF). These solutions, which are colorless, are used for reductions and hydroboration, reactions that are useful in synthesis of organic compounds. A common alternative to BHF•THF is borane–dimethylsulfide, which has a longer shelf life and effects similar ...
It is a colorless or white liquid but is typically marketed and used as a THF solution. [2] The related reducing agent sodium triethylborohydride is commercially available as toluene solutions. LiBHEt 3 is a stronger reducing agent than lithium borohydride and lithium aluminium hydride .
2-Methyltetrahydrofuran (2-MeTHF) is an organic compound with the molecular formula C 5 H 10 O. It is a highly flammable, mobile liquid. It is mainly used as a replacement for Tetrahydrofuran (THF) in specialized applications for its better performance, such as to obtain higher reaction temperatures, or easier separations (as, unlike THF, it is not miscible with water).
Terathane container owned by DuPont (before the business was sold to Invista). The main use of polytetrahydrofuran is to make elastic fibres such as spandex (elastane) for stretchable fabrics [4] and for polyurethane resins.
Osmeth can be dissolved in tetrahydrofuran (THF) and diluted in an aqueous buffer solution to make a dilute (0.25%) working solution of OsO 4. [18] With tert-BuNH 2, the imido derivative is produced: OsO 4 + Me 3 CNH 2 → OsO 3 (NCMe 3) + H 2 O. Similarly, with NH 3 one obtains the nitrido complex: OsO 4 + NH 3 + KOH → K[Os(N)O 3] + 2 H 2 O
