Chemical Structure

BOc-l-leucine-o cesium salt CAS 42538-67-0 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 BOc-l-leucine-o cesium salt.

BOc-l-leucine-o cesium salt (CAS 42538-67-0), molecular formula C11H20NO4Cs and molecular weight 363.19 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, BOc-l-leucine-o cesium salt (C11H20NO4Cs) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.5, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 363.19 g/mol, it falls into the moderately-high-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.

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 BOc-l-leucine-o cesium salt 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.
