3-(cyclohexylamine)-1-Propanesulfonic acid, referred to as CAPS, is an important chemical raw material. There are two types of manufacturers, one is for industrial purposes, the purity is relatively low, and the impurity content is too much. It is specifically for the field of biochemical reagents, with high purity and low impurity content. There are also two types involved.
English name) :3-(cyclohexylamine)-1-propanesulfonic acid
Chinese name: 3-(cyclohexylamine)-1-propanesulfonic acid
Molecular weight :221.32
Molecular formula :C9H19NO3S
Storage conditions:Room temperature, protected from light and moisture
In the industrial field:
It is mainly used to improve water-based coatings. In water-based polyisocyanate coatings, after adding CAPS, its sulfonic acid group reacts with the tertiary amine neutralizer to form sulfonic acid urea derivatives. The isocyanate coating after stability is better, the finished product is not turbid, and the dispersion state of forming latex in water is good.
In addition to being used in water-based coatings, CAPS is also often used in the manufacture of soldering fluxes, heat exchange carriers for air-conditioning equipment, raw materials for lithium metal manufacturing processes, pyrotechnics, dry batteries, etc., which are widely used.
In the field of biochemistry:
Mainly used as a biological buffer, because it is a sulfamate, it has amphotericity and can maintain the pH of the reaction system, so it has a buffering effect. The buffer range is 9.7-11.1. CAPS itself is slightly acidic. Weigh a certain amount to make an aqueous solution during configuration, then mix it with sodium hydroxide solution in proportion, and adjust the proportion according to the required pH.
When used as a buffer, CAPS is mainly used in WB experimental protein electrophoresis buffer, and is suitable for high molecular weight proteins. CAPS electrophoresis buffer is composed of CAPS, EDTA and methanol. It can be used for protein separation, protein PVDF transfer membrane, protein sequencing. It is not suitable for nylon membrane. Tris electrophoresis solution for nylon membrane. In addition, CAPS is also used in buffers for HPLC separation of basic drugs.
Desheng Technology is a manufacturer specializing in the production of CAPS reagents. Its products are mainly used as buffers in the biochemical field. It can also provide industrial-grade CAPS. The reagent grade has high purity and low impurity content. It can be directly used in kits. Other buffers such as Bicine, Tris, MOPS, etc. are also widely recognized.
