Chemical Structure

CP 1282 CAS 69712-30-7 chemical structure

Description

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.

CP 1282 (CAS 69712-30-7) is a high-purity analytical reference standard with the molecular formula C17H17N7O8S4 and a molecular weight of 575.62 g/mol.

Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, CP 1282 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 575.62 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

As a certified reference material (CRM), CP 1282 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.
