Description

General description

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.

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.

It is a primary degradation product of the widely used antipyretic and analgesic drug acetaminophen, also known as paracetamol, formed on its hydrolysis.

Application

This pharmaceutical secondary standard can also be used as follows:

• Separation and estimation of acetaminophen and its process impurities in commercial acetaminophen tablets using high-performance liquid chromatography (HPLC)
• Simultaneous electrochemical determination of acetaminophen and its impurity K using a reduced graphene oxide-titanium nitride (RGO-TiN) nanohybrid
• Development and validation of HPLC-based stability indicating method for the determination of acetaminophen, chlorpheniramine maleate, and their possible degradation products in an over-the-counter syrup formulation
• Determination of acetaminophen, pamabrom, and their impurities using high-performance thin layer chromatography (HPTLC) and reversed phase-high performance liquid chromatography (RP-HPLC), according to the ICH guidelines, in their combined dosage tablets
• Combined analysis of acetaminophen, chlorzoxazone, and their major degradation impurities using thin-layer chromatographic (TLC)-densitometric method in their combined dosage capsules

Analysis Note

These secondary standards offer multi-traceability to the USP, EP (PhEur) and BP primary standards, where they are available.
