D-cysteine hydrochloride anhydrous - Introduction
D-cysteine hydrochloride (D-cysteine) is an organic compound with the chemical formula C3H7NO2S · HCl. It is a white crystalline powder that dissolves easily in water.
D-cysteine hydrochloride anhydrogen has an antioxidant effect and can help reduce the damage of free radicals in cells. Therefore, it is widely used in anti-aging and antioxidant products in the pharmaceutical and skin care industries.
D-cysteine hydrochloride anhydride can be prepared by two methods:
1. D-Cysteine was dissolved in hydrochloric acid, followed by crystallization to obtain the D-cysteine hydrochloride anhydrogen.
2. hydrochloride anhydrogen was D-cysteine by L-cysteine extraction, and selective reduction was carried out by structural chemistry method.
As for safety, D-cysteine hydrochloride anhydrogen is relatively safe under normal use. However, excessive use may trigger some unpleasant symptoms, such as nausea, vomiting, and diarrhea. Before use, it is recommended to read the product description and consult a professional for advice.
