CAS :Produit contrôléDelta6-Testosterone is a natural steroid hormone that belongs to the group of steroid drugs. It is a potent androgen, or male sex hormone, which stimulates the development and maintenance of male sexual characteristics, including the growth of prostate gland and seminal vesicles. The effects of Delta6-testosterone are mediated by binding to and activating the Androgen Receptor (AR). The effects may also be increased when Delta6-testosterone binds to AR in combination with other hormones such as estradiol. Delta6-Testosterone is metabolized by the liver into testosterone through the cytochrome p450 enzyme system. This process begins with conversion of Delta6-testosterone into 6alpha-dihydrotestosterone (DHT) by 5a-reductase. DHT can then be converted into testosterone by 3beta-hydroxysteroid dehydrogenase/3alpha-hydroxysteroid dehydrogenase (3betaHSD) or 17beta hydFormule :C19H26O2Degré de pureté :Min. 95%Masse moléculaire :286.41 g/mol6-Bromo-1,2,3,4-tetrahydronaphthalen-2-ylamine hydrochloride

CAS :Bromocresol purple sodium salt is a dye that emits light when it is irradiated with light of a particular wavelength. It has been used to detect amniotic fluid contamination in the laboratory and as an absorber in polymer films. Bromocresol purple sodium salt absorbs ultraviolet and visible light, which causes it to emit red light. The molecules of bromocresol purple sodium salt are long-chain triazoles, which absorb water vapor and emit infrared radiation. This property can be used to detect the presence of alkali metals. The luminescent property of bromocresol purple sodium salt can be enhanced by adding an alkali metal, such as potassium or lithium chloride, to the solution where it is dissolved.
