Description

• General description: Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.N-Acetyl-L-cysteine is an endogenous aminothiol which is a component of human plasma and urine.[1] It finds use in clinical applications as a mucolytic agent typically administered by inhalation.[2]
• Application: N-Acetyl-L-cysteine may be used as a pharmaceutical reference standard for the determination of the analyte in pharmaceutical formulations by liquid chromatography-mass spectrometry (LC-MS)[3] and spectrophotometric[1] techniques.
• Biochem/physiol Actions: Antioxidant and mucolytic agent. Increases cellular pools of free radical scavengers. Reported to prevent apoptosis in neuronal cells but induce apoptosis in smooth muscle cells. Inhibits HIV replication. May serve as a substrate for microsomal glutathione transferase.
• Analysis Note: These secondary standards offer multi-traceability to the USP, EP (PhEur) and BP primary standards, where they are available.
• Other Notes: This Certified Reference Material (CRM) is produced and certified in accordance with ISO 17034 and ISO/IEC 17025. All information regarding the use of this CRM can be found on the certificate of analysis.
