Bismuth Subcarbonate is an inorganic bismuth compound supplied as a chemical raw material and pharmaceutical intermediate, also commonly referred to as basic bismuth carbonate, bismuth oxycarbonate, or bismuth carbonate hydroxide in technical documentation. Identified by CAS 5892‑10‑4, it consists of bismuth ions coordinated with carbonate and oxide groups, resulting in a stable, high‑atomic‑number solid suitable for formulated systems. The material is typically applied as a pharmaceutical excipient in industrial manufacturing processes where chemical inertness and radiopacity are required. From a supply perspective, it is provided with competitive factory pricing, customized specifications, and complete documentation including MSDS, TDS, COA, suitable for regulated bulk supply for industrial use.

FAQ - Technical & Supply Chain
-
Q:
Are bismuth subcarbonate and basic bismuth carbonate the same substance?
A: Yes. Both names refer to the same inorganic bismuth compound and correspond to the same CAS number. -
Q:
Is bismuth subcarbonate supplied as an excipient rather than a finished pharmaceutical product?
A: Yes. It is typically supplied as a raw material intended for further pharmaceutical formulation. -
Q:
Is bismuth subcarbonate commonly used for radiopaque applications in formulations?
A: It is commonly used where radiopacity is required due to the presence of bismuth, while remaining chemically stable in solid systems.
