What is of 1-acetyl-2-phenylhydrazine with cas 114-83-0?

1-Acetyl-2-phenylhydrazine is an amide and an amine. Organic amides/imides react with azo and diazo compounds to generate toxic gases. Flammable gases are formed by the reaction of organic amides/imides with strong reducing agents. Amides are very weak bases (weaker than water). Imides are less basic yet and in fact react with strong bases to form salts. That is, they can react as acids. Mixing amides with dehydrating agents such as P2O5 or SOCl2 generates the corresponding nitrile. The combustion of these compounds generates mixed oxides of nitrogen (NOx).

What is Polycaprolactone CAS 24980-41-4?

Polycaprolactone (PCL) CAS 24980-41-4 is a biodegradable, semicrystalline polyester for use in tissue engineering and drug delivery research applications. Due to the increased length of the aliphatic chain, polycaprolactone degrades significantly slower than other common biodegradable polymers, such as polylactide. PCL features a low melting point (55-60 °C), making it ideal for thermal processing and increasing its use in novel applications such as 3D bioprinting.

What is Phenolphthalein CAS 77-09-8?

Phenolphthalein CAS 77-09-8 mainly acts on the large intestine, which produces semi-liquid excreta in 4 to 8 hours with little or no colic. The claim that yellow phenolphthalein is three times stronger than white remains unproven. As a result of enterohepatic circulation, the effect of a single dose is sustainable for 3 to 4 days. The drug is an active member of many laxatives that can be sold legally without prescription.

What is Indene CAS 95-13-6？

Indene, also known as benzocyclopropene, is a polycyclic aromatic hydrocarbon with low toxicity and irritation to human skin and mucous membranes. It exists naturally in coal tar and crude oil. In addition, indene is also released when mineral fuels are not completely burned. Molecular formula C9H8. Molecular weight 116.16. The benzene ring and cyclopentadiene in its molecule share two adjacent carbon atoms. It appears as a colorless liquid, does not volatilize in vapor, turns yellow when standing still, but loses color when exposed to sunlight. Melting point -1.8°C, boiling point 182.6°C, flash point 58°C, relative density 0.9960 (25/4°C); insoluble in water, miscible with ethanol or ether. Indene molecules contain highly chemically active olefin bonds, which are prone to polymerization or addition reactions. Indene can polymerize at room temperature, and heating or in the presence of an acidic catalyst can increase the polymerization rate sharply, and react with concentrated sulfuric acid to form secondary indene resin. Indene is catalytically hydrogenated (see catalytic hydrogenation reaction) to form dihydroindene. The methylene group in the indene molecule is similar to the methylene group in the cyclopentadiene molecule. It is easily oxidized and reacts with sulfur to produce a complex, which has a weak acid reaction and reducing properties. Indene reacts with metallic sodium to form sodium salt, and condenses with aldehydes and ketones (see condensation reaction) to form benzofulvene: Indene is separated from the light oil fraction obtained from the distillation of coal tar in industry.

Appearance	Yellow liquid	Conforms
Indene	>96%	97.69%
Benzonitrile	<3%	0.83%
Water	<0.5%	0.04%

Application

Indene is mainly used to produce indene-coumarone resin. The raw material of indene-coumarone resin is the 160-215°C fraction distilled from heavy benzene and light oil fractions, which roughly contains 6% styrene, 4% coumarone, 40% indene, 5% 4-methylstyrene and a small amount of xylene, toluene and other compounds. The total amount of resin accounts for 60-70% of the Chemicalbook raw materials. Under the action of catalysts such as aluminum chloride, boron fluoride or concentrated sulfuric acid, indene and coumarone fractions are polymerized under pressure or without pressure to generate indene-coumarone resin. It can be mixed with other liquid hydrocarbons as a coating solvent. It can also be an intermediate of pesticides or mixed with other liquid hydrocarbons as a coating solvent.

what is of DL-Mandelic acid with cas 90-64-2?

Mandelic acid is a high molecular weight fruit acid with lipophilicity. Compared with the common fruit acid glycolic acid, mandelic acid has a certain antibacterial ability. At the same time, compared to common glycolic acids and lactic acids, its transdermal speed will be slower, which means that the irritation is less than that of glycolic acids. Its fat solubility increases, and the transdermal ability of the stratum corneum is improved. Like glycolic acid and lactic acid, mandelic acid also has a certain whitening effect.

The calcium salt form is more stable than free HMB, not easy to absorb moisture or degrade, and has a longer shelf life, making it suitable for powder or capsules.

2.Dual biological activity
It provides HMB (leucine metabolite) and calcium ions at the same time, taking into account muscle metabolism regulation and bone health support.

3.Slow-release absorption
Calcium salts gradually dissociate in the intestines, and HMB is released more slowly, which may prolong the duration of action.
