How to control the purity of Dimethylthiocarbamoyl chloride?

Reagents are divided by purity (how much impurity content), mainly divided into guarantee reagent purity, analytical purity, chemical purity and experimental reagents, in addition to high purity, spectral purity, benchmark reagents these three categories.

①GR reagent: Also known as first grade or assurance reagent, 99.8%, this reagent has the highest purity and the lowest impurity content, suitable for important and precise analytical work and scientific research work, using green bottle labels.

②AR reagent: Also known as secondary reagent, high purity, 99.7%, slightly inferior to grade pure, suitable for important analysis and general research work, use red bottle.

③CP reagent: Also known as tertiary reagent, ≥ 99.5%, the purity and analytical purity of a large difference, suitable for mining, school general analysis work. Use the blue label.

④LR reagent: Also called iv reagent.

⑤EP reagent: Reagent with much higher purity than gr (≥ 99.99%).

⑥SP reagent: Spectral purity. But because the organic matter is not shown on the spectrum, so sometimes the principal component can not reach more than 99.9%, when using must pay attention, especially as a reference, must be calibrated.

⑦PT reagent: Specially used as reference material, can be directly prepared standard solution.

Dimethylthiocarbamoyl chloride is a kind of Heterocyclic series intermediate. It is light yellow to yellow crystal with a purity higher than 98%.
