Description
Carbocysteine Product Overview
Carbocysteine (S-carboxymethyl-L-cysteine, C5H9NO4S) is a white crystalline powder that is practically insoluble in water but dissolves in dilute acids and alkalis. It is derived from the amino acid L-cysteine, and its optical purity is controlled by specific rotation.
Pharmaceutical companies use it in syrups, oral solutions, capsules and granules in the mucolytic class. Because it dissolves poorly in water, liquid formulations usually adjust the pH with a base to form a soluble salt. Related mucolytic APIs in our range include Bromhexine Hydrochloride and Ambroxol hydrochloride.
Zyntex supplies it from qualified API producers with lot-specific documentation, only to licensed pharmaceutical companies.

Frequently Asked Questions
How is carbocysteine dissolved in syrups?
It dissolves poorly in water, so formulators raise the pH with a base such as sodium hydroxide to form a soluble salt.
Who can purchase this API?
It is supplied only to pharmaceutical companies holding the licenses required for API purchase and use in their country.
How can I get a price and documents?
Prices depend on quantity, packaging and destination. Contact us with your required volume to receive a quotation together with the CoA and SDS.
