Amoxicillin Related Compound C - USP CRS is a chemically synthesized analog of amoxicillin, primarily used as a reference standard in pharmaceutical research, analytical method validation, and quality control testing for drug development. This compound is structurally similar to amoxicillin but lacks its full antibiotic activity, making it ideal for precise analytical work. This reference standard has a CAS number of 94659-47-9, with the molecular formula C16H19N3O5S and a molecular weight of 365.40 g/mol. It must be stored between 2°C and 8°C and carries a **Danger** signal word due to its hazardous properties. Molekula supplies Amoxicillin Related Compound C - USP CRS from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
