SB-277011A, >98% (HPLC) CAS 215803-78-4 chemical structure

Description

CATO supplies SB-277011A, >98% (HPLC) (CAS 215803-78-4), a certified reference material (molecular formula C28H30N4O, MW 438.56 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, SB-277011A, >98% (HPLC) is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 438.56 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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 SB-277011A, >98% (HPLC) 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.
