Chemical Structure

Cycloserine Impurity 5 HCl CAS 112346-82-4 chemical structure

Description

Cycloserine Impurity 5 HCl (CAS 112346-82-4) is a certified pharmaceutical impurity reference standard with the molecular formula C4H8ClNO2HCl and a molecular weight of 174.02 g/mol.

Structurally, Cycloserine Impurity 5 HCl (C4H8ClNO2HCl) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 174.02 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

As a certified reference material (CRM), Cycloserine Impurity 5 HCl 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.
