Description

CATO supplies 1-piperazineacetic acid, 4-[(1,1-dimethylethoxy)carbonyl]-alpha-(2-fluorophenyl)- 2 - (4 - Boc - piperazinyl) - 2 - (2 - fluoro - phenyl)acetic acid 4-[Carboxy-(2-fluoro-phenyl)-methyl]-piperazine-1-carboxylic acid tert-butyl ester 444892-80-2 [4-(tert-butoxycarbonyl)-1-piperazinyl](2-fluorophenyl)acetic acid (CAS 444892-80-2), a certified reference material (molecular formula C17H29FN2O4, MW 344.42 g/mol) for analytical method development and quality control.

The molecular framework of 1-piperazineacetic acid, 4-[(1,1-dimethylethoxy)carbonyl]-alpha-(2-fluorophenyl)- 2 - (4 - Boc - piperazinyl) - 2 - (2 - fluoro - phenyl)acetic acid 4-[Carboxy-(2-fluoro-phenyl)-methyl]-piperazine-1-carboxylic acid tert-butyl ester 444892-80-2 [4-(tert-butoxycarbonyl)-1-piperazinyl](2-fluorophenyl)acetic acid (C17H29FN2O4) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

CATO manufactures 1-piperazineacetic acid, 4-[(1,1-dimethylethoxy)carbonyl]-alpha-(2-fluorophenyl)- 2 - (4 - Boc - piperazinyl) - 2 - (2 - fluoro - phenyl)acetic acid 4-[Carboxy-(2-fluoro-phenyl)-methyl]-piperazine-1-carboxylic acid tert-butyl ester 444892-80-2 [4-(tert-butoxycarbonyl)-1-piperazinyl](2-fluorophenyl)acetic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
