Chemical Structure

Cefazolin Impurity 36 CAS 5456-21-3 chemical structure

Description

As a certified reference material (CRM), Cefazolin Impurity 36 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

Cefazolin Impurity 36 (CAS 5456-21-3) is a high-purity analytical reference standard with the molecular formula CH4N2S2H3N and a molecular weight of 125.21 g/mol.

Owing to sulfur-containing functionality, Cefazolin Impurity 36 is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 125.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
