(S)-4-((tert-Butoxycarbonyl)amino)-2-(3-((2-isopropylthiazol-4-yl)methyl)-3-methylureido)butanoic acid CAS 1004316-84-0 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (S)-4-((tert-Butoxycarbonyl)amino)-2-(3-((2-isopropylthiazol-4-yl)methyl)-3-methylureido)butanoic acid.

(S)-4-((tert-Butoxycarbonyl)amino)-2-(3-((2-isopropylthiazol-4-yl)methyl)-3-methylureido)butanoic acid (CAS 1004316-84-0), molecular formula C18H30N4O5S and molecular weight 414.52 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (S)-4-((tert-Butoxycarbonyl)amino)-2-(3-((2-isopropylthiazol-4-yl)methyl)-3-methylureido)butanoic acid (C18H30N4O5S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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 (S)-4-((tert-Butoxycarbonyl)amino)-2-(3-((2-isopropylthiazol-4-yl)methyl)-3-methylureido)butanoic 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.
