Analysis Reagents


Chlorotrimethylsilane have been used in the preparation of volatile derivatives of a wide range of compounds for GC analysis. Chlorotrimethylsilane has been used for silylation and as a protection group in the process of various organic synthesis.


Used as a solvent in various organic synthesis conversion reactions; used to study the formation of stable functionalized hydride silane diradical transition metal complexes from arylsilanes through photochemistry; aprotic dipolar solvents, often used as carcinogens HMPA substitution

HEPES (4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid ) is a zwitterionic organic chemical buffering agent; one of the twenty Good's buffers. HEPES is widely used in cell culture, largely because it is better at maintaining physiological pH despite changes in carbon dioxide concentration (produced by cellular respiration) when compared to bicarbonate buffers, which are also commonly used in cell culture. The dissociation of water decreases with falling temperature, but the dissociation constants (pK) of many other buffers do not change much with temperature. HEPES is like water in that its dissociation decreases as the temperature decreases. This makes HEPES a more effective buffering agent for maintaining enzyme structure and function at low temperatures. Lepe-Zuniga et al. reported a phototoxicity of HEPES when exposed to ambient light by the production of hydrogen peroxide, which is not a problem in bicarbonate-based cell culture buffers. It is therefore strongly advised to keep HEPES-containing solutions in darkness as much as possible.HEPES has the following characteristics:

Substance is used in analytical chemistry as a sensitive reagent for reducing sugars, and to distinguish between ketols and simple aldehydes.

Sweet Almond oil

Pharmaceutic aid (emollient and perfume); pharmaceutic aid (vehicle, oleaginous). almond oil, sweet (Prunus amygdalus dulcis) is serves as an emollient and a carrier, providing an elegant skin feel and promoting spreadability in creams, lotions, and bath oils. Sweet almond oil’s main constituent is olein with a small proportion of linoleic acid glyceride. It is obtained from sweet almonds that have undergone a cleaning and crushing process, leaving them in powder form. The powder is then cold-pressed and left to “rest” for one to two weeks. After the resting period, the almond oil is filtered and often bleached. Sweet almond oil is the triglyceride oil (vegetable oil) derived from almonds, and is very similar in composition to olive oil. sweet almond oil is an emollient with soothing properties. Almond Oil is the oil of the bitter almond after the removal of hydro- cyanic acid. it is a colorless to slightly yellow liquid having a strong principally almond-like aroma. it is used mainly in the pharmaceu- tical and cosmetic industry and also as a food flavoring agent.

Analytical reagents generally refer to chemical reagents, which are relatively standard substances for chemical research and component analysis, and are important conditions for scientific and technological progress. They are widely used in the synthesis, separation, qualitative and quantitative analysis of substances. Chemicals are indispensable in the daily work of factories, schools, hospitals and research institutes.
