Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2S)-2-[[(2S)-2-Amino-3-[3-[Bis(2-Chloroethyl)Amino]Phenyl]Propanoyl]-[(2S)-Pyrrolidine-2-Carbonyl]Amino]-3-(4-Fluorophenyl)Propanoic Acid.

(2S)-2-[[(2S)-2-Amino-3-[3-[Bis(2-Chloroethyl)Amino]Phenyl]Propanoyl]-[(2S)-Pyrrolidine-2-Carbonyl]Amino]-3-(4-Fluorophenyl)Propanoic Acid (CAS 38305-84-9), molecular formula C27H33Cl2FN4O4 and molecular weight 567.48 g/mol, is a CATO reference standard with documented purity and traceability.

(2S)-2-[[(2S)-2-Amino-3-[3-[Bis(2-Chloroethyl)Amino]Phenyl]Propanoyl]-[(2S)-Pyrrolidine-2-Carbonyl]Amino]-3-(4-Fluorophenyl)Propanoic Acid (C27H33Cl2FN4O4) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

As a certified reference material (CRM), (2S)-2-[[(2S)-2-Amino-3-[3-[Bis(2-Chloroethyl)Amino]Phenyl]Propanoyl]-[(2S)-Pyrrolidine-2-Carbonyl]Amino]-3-(4-Fluorophenyl)Propanoic Acid 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.
